Phys. Rev. C 12, 877 (1975) - Published 1 September, 1975

Show Abstract

Angular distributions have been obtained for the ${}^{144}{Sm}$ ( ${}^{13}C$ , ${}^{13}C$ ) ${}^{144}{Sm}_{g . s .}$ , ${}^{144}{Sm}$ ( ${}^{13}C$ , ${}^{14}C$ ) ${}^{143}{Sm}_{0.75}$ , and ${}^{144}{Sm}$ ( ${}^{13}C$ , ${}^{14}C$ ) ${}^{143}{Sm}_{1.10}$ reactions at 66 MeV. In addition, several states in ${}^{143}{Sm}$ and ${}^{145}{Sm}$ were identified by bombardment of ${}^{144}{Sm}$ in the reactions ( ${}^{13}C$ , ${}^{14}C$ ) and ( ${}^{13}C$ , ${}^{12}C$ ), respectively, at 72 MeV for $θ_{lab} = 50 °$ . Optical model parameters were deduced and a full finite-range recoil distorted-wave Born approximation analysis provided $C^{2} S$ values and $J^{π}$ assignments for levels in ${}^{143}{Sm}$ and ${}^{145}{Sm}$ . The use of heavy-ion reactions in conjunction with light ion results is shown to be a useful nuclear spectroscopic tool.

Show Abstract

The ${}^{12}C ({}^{12}C, p γ) {}^{23}{Na}$ reaction, at an incident energy of $E_{c . m .} = 19.3$ MeV, has been used to study the $γ$ -ray decay of the 9.042 and 9.806 MeV levels in ${}^{23}{Na}$ , which are resonantly excited at this energy. Doppler shift attenuation measurements have yielded lifetime limits of $τ < 10$ fs for the 9.042 MeV level and $τ < 20$ fs for the 9.806 MeV level. Angular distributions of the $γ$ rays deexciting these two levels have been measured, and the results are consistent with the assumption of $J = \frac{15}{2}$ and $J = \frac{17}{2}$ , respectively. The measurements indicate that these two levels are likely candidates for the ${\frac{15}{2}}^{+}$ and ${\frac{17}{2}}^{+}$ members of the ground state rotational band in ${}^{23}{Na}$ .

${}^{208}{Pb}$ ( ${}^{16}O$ , ${}^{15}O$ ) ${}^{209}{Pb}$ reaction

F. D. Becchetti, B. G. Harvey, D. Kovar, J. Mahoney, C. Maguire, and D. K. Scott

Phys. Rev. C 12, 894 (1975) - Published 1 September, 1975

Show Abstract

The neutron levels in ${}^{209}{Pb}$ have been studied with the ${}^{208}{Pb}$ ( ${}^{16}O$ , ${}^{15}O$ ) reaction at a bombarding energy of 139 MeV. Spectroscopic factors ( $S$ ) have been deduced using a finite-range distorted-wave Born approximation (DWBA) with recoil. The $2 g_{\frac{9}{2}}$ , $1 i_{\frac{11}{2}}$ , $2 g_{\frac{7}{2}}$ , and $3 d_{\frac{3}{2}}$ levels are found to have $S ≳ 0.9$ while $S \approx 0.7$ for the $1 j_{\frac{15}{2}}$ level at 1.4 MeV excitation. Evidence is found for other $1 j_{\frac{15}{2}}$ fragments being at 3.05 MeV and ∼ 3.8 MeV with $S \approx 0.08 and 0.26$ , respectively, which would place the centroid of the $1 j_{\frac{15}{2}}$ level at $E_{x} \approx 2.2$ MeV. DWBA predicts a shift in the maxima of the angular distributions as a function of $Q$ value which is not observed experimentally. A comparison with the proton transfer reaction ${}^{208}{Pb}$ ( ${}^{16}O$ , ${}^{15}N$ ) ${}^{209}{Bi}$ has been used to deduce the geometrical parameters of a neutron shell-model potential appropriate for nuclei with $A ≳ 200$ . The parameters of this Woods-Saxon potential are: $V_{R} = - 50.5$ MeV $r_{R} = 1.19$ fm, $a_{R} = 0.75$ fm, $V_{so} = - 5.5$ MeV, $r_{so} = 1.01$ fm, and $a_{so} = 0.75$ fm.

Relativistic effects in bound-state form factors

R. M. Woloshyn

Phys. Rev. C 12, 901 (1975) - Published 1 September, 1975

Show Abstract

The formalism for bound-state form factors in a three-dimensional relativistic theory is used to expose the theoretical limitations of recent work on meson exchange currents. The pair excitation and recoil emission currents used in phenomenological calculations are found to have little theoretical support. The constraints imposed by the Ward identity are examined and the singularity structure of the form factor in relativistic and nonrelativistic theories is compared.

Propagation in nonlocal optical potentials

F. Lenz and E. J. Moniz

Phys. Rev. C 12, 909 (1975) - Published 1 September, 1975

Show Abstract

We show that a nonlocal optical potential implies multiple eigenmode propagation. This is important when the mean free path becomes of the order of the nonlocality, such as in the strong absorption situation occurring for pion scattering near the 3-3 resonance, and consequently the propagation cannot be described reasonably by one complex wave number. The eigenmode structure can be seen most directly in quasielastic scattering.

Excitation of giant magnetic and spin-isospin dipole states in radiative $π$ capture on ${}^{14}N$ and ${}^{10}B$

Helmut W. Baer, James A. Bistirlich, Nico de Botton, Susan Cooper, Kenneth M. Crowe, Peter Truöl, and John D. Vergados

Phys. Rev. C 12, 921 (1975) - Published 1 September, 1975

Show Abstract

The photon spectra in the capture of stopped pions on ${}^{14}N$ and ${}^{10}B$ were measured in the 50-150-MeV region with a high-resolution pair spectrometer. The total radiative capture branching ratios are 2.13±0.21 and 2.27±0.22%, respectively. The spectrum corresponding to the first 13 MeV excitation in each of the residual nuclei ${}^{14}C$ and ${}^{10}{Be}$ is dominated by the transition to the analog of a giant $M 1$ state of the target nucleus. The ground state transitions in both nuclei are resolved experimentally. The measured branching ratio for the extremely weak ${}^{14}C$ (g.s.) transition is (3±2) × $10^{- 5}$ . There is evidence for selective excitation of the analogs of the giant dipole spin-isospin states of ${}^{14}N$ , of which the $3^{-}$ component appears to be the strongest. In ${}^{10}B$ the transition strength to the giant resonance region is more fragmented. An analysis is presented that employs an impulse-approximation Hamiltonian with amplitudes taken directly from the fundamental process on the nucleon, $π^{-} + p \to n + γ$ , and shell-model wave functions obtained using realistic interactions in the $1 s$ , $1 p$ , and $2 s - 1 d$ shells. Also, a calculation for the ${}^{14}C$ (g.s.) transition from $1 s$ capture using the "elementary-particle soft-pion" ansatz is presented.

Charge dispersion and recoil properties at $A = 131$ from the interaction of ${}^{197}{Au}$ with 11.5- and 300-GeV protons

Y. W. Yu and N. T. Porile

Phys. Rev. C 12, 938 (1975) - Published 1 September, 1975

Show Abstract

Cross sections and thick-target recoil properties of five nuclides with $A = 131$ as well as those of a number of neighboring nuclides have been determined for the interaction of ${}^{197}{Au}$ with 11.5-GeV protons. The charge dispersion at $A = 131$ has a single peak at $Z_{A} - Z = - 3.5$ and the total isobaric cross section is 8.9 ± 0.8 mb. The ranges indicate that only ∼2% of this value can be ascribed to fission, the bulk of the cross section involving a deep spallation process. Similar data have been obtained at 300 GeV. Within the limits of error the results are the same at both energies. The systematics of deep spallation reactions are examined.

Show Abstract

The nucleon-deuteron breakup reaction is analyzed in the framework of a model of single and double scattering using the off-shell $t$ -matrix elements corresponding to several realistic local two-nucleon potentials. The multiple scattering contributions are estimated through a model derived from a fixed scattering centers approximation with a simple separable two-body $t$ matrix.

Internal conversion studies in ${}^{144}{Nd}$

F. T. Avignone, III and S. Raman

Phys. Rev. C 12, 963 (1975) - Published 1 September, 1975

Show Abstract

The relative electron intensities of eight transitions in ${}^{144}{Nd}$ were measured with a combination magnetic-Si(Li) spectrometer. The deduced internal conversion coefficients were compared with theoretical values in order to determine the multipolarity assignments for these transitions. With the assumption that the 618.0-keV transition is $E 2$ , the 476.8-, 582.4-, and 696.5-keV transitions were also found to be $E 2$ . The 301.7-, 778.6-, and 814.1-keV transitions were found to be predominantly $E 1$ . Our results are consistent with an $E 0 + M 1 + E 2$ assignment for the 890.1-keV transition. The internal conversion studies confirm the spin and parity assignments for four excited states in ${}^{144}{Nd}$ which were previously proposed mainly on the basis of angular correlation measurements.

Induced weak currents and $β^{\pm} - α$ angular correlations in $A = 8$

R. E. Tribble and G. T. Garvey

Phys. Rev. C 12, 967 (1975) - Published 1 September, 1975

Show Abstract

$β - α$ angular correlations of the form $ω (θ_{β α}) = 1 + a {cos θ}_{β α} + p {{cos}^{2} θ}_{β α}$ have been measured as a function of $β$ energy for the two decays ${}^{8}{Li} \overset{β}{\to} {}^{8}{Be} \to 2 α$ . and ${}^{8}B \overset{β}{\to} {}^{8}{Be} \to 2 α$ . The results of the angular correlations are considered in a model independent analysis, along with a comparison to model dependent wave function calculations. The $a$ coefficient is a kinematic term that depends on $〈 \frac{1}{v^{*}} 〉$ , where $v^{*}$ is the center of mass velocity of the $α$ particle. A detailed comparison between the experimental results and the theoretical prediction for $a$ shows that the measured kinematic term is (10-15)% smaller than the prediction. The $p$ coefficients arise from induced weak currents. Utilizing the $G$ -parity properties of these currents, we discuss the results corresponding to $δ_{\pm} = p_{{}^{8}{Li}} \pm p_{{}^{8}B}$ . The second order $β$ energy dependence in $δ_{-}$ is found to be negligible. Assuming no second order energy dependence, the experimental result is $\frac{(δ_{-}) m_{n}}{E_{β}} = 7.0 \pm 0.5 = (\frac{b}{Ac}) - (\frac{d_{II}}{AC})$ , where $b$ and $d_{II}$ are the weak magnetism and second class currents, and $c$ is the Gamow-Teller current. The experimental result for $\frac{(δ_{+}) m_{n}}{E_{β}}$ determines the first class induced tensor current $d_{I}$ , and the second forbidden axial currents $j_{2}$ and $j_{3}$ . The interpretation of $\frac{(δ_{+}) m_{n}}{E_{β}}$ is complicated since wave function predictions indicate that all three currents should contribute significantly to $δ_{+}$ .

Mechanisms contributing to $K$ electron ejection in nuclear $β$ decay

J. Law and J. L. Campbell

Phys. Rev. C 12, 984 (1975) - Published 1 September, 1975

Show Abstract

Theoretical calculations of shake-off and shake-up autoionization probabilities for $K$ electrons are presented, using the formalism presented previously. Total $K$ electron ejection probabilities $P_{K}$ are obtained by summing shake-off and shake-up contributions. The role of direct collision is discussed. Agreement between these $P_{K}$ values and 33 recent experimental results produced by different techniques is generally good. The comparison permits critical assessment of the remaining weaknesses of the theory.

Sources were produced via the ${}^{141}\Pr ({}^{3}{He}, 4 n)$ ) reaction. The study of ${}^{140}{Pm}^{g}$ decay utilized a helium-jet recoil transport system. Fourteen $γ$ rays were assigned ${}^{140}{Pm}^{m}$ decay and nine were attributed to ${}^{140}{Pm}^{g}$ decay. Decay schemes of ${}^{140}{Pm}^{m}$ and ${}^{140}{Pm}^{g}$ were constructed. Evidence for the low-spin members of the two-phonon triplet in ${}^{140}{Nd}$ is also presented.

Reaction ${}^{3}{He} (d, t) 2 p$ at 23.5 MeV center of mass

R. W. Rutkowski and E. E. Gross

Phys. Rev. C 12, 362 (1975) - Published 1 August, 1975

Show Abstract

We have measured the absolute spectra for the yield of high-energy tritons for the process ${}^{3}{He} (d, t) 2 p$ at 24 MeV c.m. Elastic scattering of deuterons from ${}^{3}{He}$ has also been measured at the same c.m. energy. The reaction data are characterized by forward and backward peaking and by a deep minimum near 90° c.m. The forward-angle triton spectrum is consistent with a simple pickup process. A comparison of the forward-angle triton yield to the cross section for elastic scattering at back angles provides strong evidence both for the dominance of the pickup process at small angles in the reaction and for the importance of this process to back-angle elastic scattering.

Phys. Rev. C 12, 378 (1975) - Published 1 August, 1975

Show Abstract

Differential cross sections have been measured for ( $p, n$ ) reactions to the isobaric analogs of the targets ${}^{48}{Ca}$ , ${}^{90}{Zr}$ , ${}^{120}{Sn}$ , and ${}^{208}{Pb}$ at proton bombarding energies of 25, 35, and 45 MeV. The isospin-flip strength of a phenomenological nucleon-nucleon force has been determined with microscopic distorted-wave calculations including the "knock-on" exchange amplitude. A realistic $G$ -matrix effective interaction also provides a reasonable account of the observed cross sections, particularly at the higher proton energies.

Show Abstract

The ${}^{98}{Mo} (p, d) {}^{97}{Mo}$ reaction has been used at a bombarding energy of 38.6 MeV to populate neutron hole states of ${}^{97}{Mo}$ . Excitation energies and angular distributions were measured for levels up to 4.5 MeV in excitation. A distorted-wave-Born-approximation analysis was used to make $l$ assignments and to obtain spectroscopic factors. Three distinct groups of weakly excited levels, one corresponding to $l = 4$ and two corresponding to $l = 1$ , were observed lying above 2.7 MeV excitation. A hole-core-coupling model is used to predict the properties of ${}^{97}{Mo}$ and ${}^{97}{Nb}$ and good agreement with the experiment is obtained.
