Coupled quadrupole-octupole excitations in ${}^{44}{Ca}$ and the decay of ${}^{44}K$ , ${}^{44}{Sc}^{m}$ , and ${}^{44}{Sc}^{g}$

G. Coleman and R. A. Meyer

Phys. Rev. C 13, 847 (1976) - Published 1 February, 1976

Show Abstract

The decay of ${}^{44}K$ , ${}^{44}{Sc}^{g}$ , and ${}^{44}{Sc}^{m}$ to levels of ${}^{44}{Ca}$ have been studied. For decay of ${}^{44}K$ , approximately 125 $γ$ rays have been observed using singles, Compton-supression, and $γ - γ$ -coincidence Ge(Li) spectroscopy. The decay data, used in conjunction with recent reaction spectroscopy data, have led to the identification of 35 levels in ${}^{44}{Ca}$ that are populated in $β$ decay. The levels below 4500 keV are discussed within the framework of multiple vibrations. The levels at $J^{π}$ in parentheses) 3661.53 ( $1^{-}$ ), 3676.07 ( $2^{-}$ ), 3711.80 ( $4^{-}$ ), 3913.8 ( $5^{-}$ ), and 4358.42 keV ( $3^{-}$ ) are suggested as the two phonon quadrupole-octupole pentad.

Phys. Rev. C 13, 859 (1976) - Published 1 February, 1976

Show Abstract

An angular momentum projection formulation in conjunction with the many-body Nilsson-BCS variational wave function is presented for the pairing plus quadrupole interaction Hamiltonian. The theory is applied to calculate the energies and half-lives of the recently observed high spin yrast states in ${}^{156, 158, 160, 162}{Er}$ and ${}^{156}{Dy}$ . The results of the calculation are in good agreement with the corresponding experimental data.

Double $β$ -decay nuclear matrix elements and lepton conservation

J. D. Vergados

Phys. Rev. C 13, 865 (1976) - Published 1 February, 1976

Show Abstract

The nuclear matrix elements involved in the double $β$ -decay of ${}^{48}{Ca}$ , ${}^{130}{Te}$ , and ${}^{128}{Te}$ were calculated using realistic nuclear interactions and shell model nuclear wave functions. The double doorway state is not appreciably mixed in the ground state of the final nuclei. So the ground state transitions contain a small fraction of the sum rule. A lepton nonconservation parameter $η ≲ 10^{- 4}$ was deduced.

Show Abstract

Lifetime and angular correlation measurements of the $γ$ decays of the 9.04- and 9.81-MeV levels in ${}^{23}{Na}$ have been performed. These results are consistent with the identification of these two states as the ${\frac{15}{2}}^{+}$ and ${\frac{17}{2}}^{+}$ members of the ${}^{23}{Na}$ ground state rotational band. These spins, together with other considerations, suggest $J^{π} = 12^{+}$ for the $E_{c . m .} = 19.3$ MeV ${}^{12}C$ + ${}^{12}C$ resonance.

Spectroscopic factors for ( $d, p$ ) stripping reactions with different repulsive core nucleon-nucleon potentials

Ahmed Osman and M. Zaky

Phys. Rev. C 13, 1 (1976) - Published 1 January, 1976

Show Abstract

Deuteron stripping reactions are considered. The short-range correlations for the nucleons in the nuclei are taken into account. The neutron-proton nuclear potential in the deuteron is taken as a long-range attractive potential surrounded by a short-range repulsive potential. We take different forms for the two parts of the neutron-proton nuclear potential. The differential cross sections for the two nuclear reactions ${}^{28}{Si} (d, p) {}^{29}{Si}$ and ${}^{40}{Ca} (d, p) {}^{41}{Ca}$ have been calculated for each of the nuclear potential forms. Fitting our theoretical calculations, with the experimental data, using the distorted-wave Born-approximation calculations, a good agreement is obtained. The more reliable spectroscopic factors for these reactions have been extracted.

The ${}^{84}{Kr} ({}^{3}{He}, α) {}^{83}{Kr}$ reaction has been studied at a bombarding energy of 18 MeV. The isotopically enriched ${}^{84}{Kr}$ target was contained in a gas cell with no entrance window. Excitation energies and angular distributions were obtained for 16 levels up to 2735 keV excitation energy in ${}_{36}^{83}{Kr}_{47}$ .

Phys. Rev. C 13, 109 (1976) - Published 1 January, 1976

Show Abstract

The level structures of ${}^{51}{Mn}$ and ${}^{53}{Mn}$ have been studied using our 100-cm broad range magnetic spectrograph and the ${}^{54}{Fe} (p, α) {}^{51}{Mn}$ and ${}^{56}{Fe} (p, α) {}^{53}{Mn}$ reactions. Precise level energies in ${}^{51}{Mn}$ have been measured up to the region of 4 MeV in excitation. Thirty-four states have been identified in this region of excitation, 10 of which have not previously been reported. The uncertainty in energy of the third excited state at 1488.9 keV has been reduced from 10 keV to 0.8 keV. We confirm the new levels at 2893 and 3049 proposed in a recent ${}^{50}{Cr} (p, γ) {}^{51}{Mn}$ experiment but do not observe levels at 2488, 2660, 2717, and 2808 reported in an earlier ${}^{50}{Cr} (p, γ)$ experiment. Using the ${}^{56}{Fe} (p, α) {}^{53}{Mn}$ reaction we have found 28 previously unreported levels in the region up to 5.1 MeV in excitation. We confirm the existence of four of the five high spin states recently reported in ${}^{50}{Cr} (α, p γ) {}^{53}{Mn}$ work at 2563.7, 2693.5, 2697.3, 3425.6, and 3440.5 keV. We were unable to resolve the 3.8-keV doublet at 2694 keV. We do not observe levels at 1940, 2448.1, 2761.0, 2967.3, and 2978.1 keV which have been proposed or observed in previous ${}^{52}{Cr} (p, γ)$ studies. In addition we did not observe the levels reported at 2370 and 3061 keV in previous ${}^{52}{Cr} ({}^{3}{He}, d) {}^{53}{Mn}$ experiments. Our ${}^{52}{Cr} ({}^{3}{He}, d) {}^{53}{Mn}$ and ${}^{52}{Cr} ({}^{3}{He}, d γ) {}^{53}{Mn}$ measurements do not show these levels.

Show Abstract

Proton energy spectra from the ${}^{54}{Cr} (α, p) {}^{57}{Mn}$ reaction at 15, 21, and 24 MeV and at several angles have been measured with the 100-cm broad-range spectrograph. Both NaI(Tl) and Ge(Li) detectors have been used to study $γ$ rays, in coincidence with protons in a particle detector, from the same reaction. From the spectrograph measurements, the ground-state $Q$ value is found to be -4308 ± 8 keV. Excited levels have been found at 84.1 ± 1.0, 851.1 ± 1.0, 1059.2 ± 2.0, 1073.8 ± 2.0, 1227.1 ± 1.0, 1376.5 ± 1.3, 2188.2 ± 1.1, and 2234.3 ± 1.7 keV. Ten $γ$ -ray transitions have been observed. From particle-γ coincidence and angular-correlation measurements the spins of some levels can be limited as follows: 84 keV, 3/2-7/2; 851 keV, 3/2 or 5/2; 1059 keV, 1/2-5/2. Probable spin assignments for these three levels suggested on the basis of cross-section and relative transition-strength considerations are (7/2), (3/2), and (1/2), respectively. Other tentative spin assignments, and the comparison of ${}^{57}{Mn}$ with other odd Mn isotopes, are discussed.

Phys. Rev. C 13, 124 (1976) - Published 1 January, 1976

Show Abstract

Neutron total cross section vs energy measurements were made for several thicknesses of bismuth metal. The results of the resonance parameter evaluation for 30 levels (12 $s$ and 18 $p$ ) to 75 keV are given. Parameters for the $p$ levels, and for three weak $s$ levels were determined using a transmission area analysis. An $R$ -matrix multilevel shape analysis fitting was used to obtain the final choice resonance parameters for the nine dominant $l = 0$ levels. The experimental points and $R$ -matrix fit curve to 75 keV are shown. The ( $E_{0}, J, Γ_{n}$ ) choices for these nine levels are (0.800, 5, 4.6), (2.312, 4, 19.5), (5.112, 5, 5.4), (12.15, 4, 270), (15.54, 4, 118), (27.08, 4, 24), (33.34, 4, 240), (45.58, 5, 160), and (69.18, 5, 520), where $E_{0}$ is in keV and $Γ_{n}$ is in eV. On the basis of these levels, we obtain for the $s$ and $p$ strength functions $10 {}^{4}S_{0} = ({0.62}_{- 0.20}^{+ 0.36})$ and $10 {}^{4}S_{1} = ({0.13}_{- 0.04}^{+ 0.06})$ . A channel radius of 9 fm was used to calculate $S_{1}$ and the evaluation ignores the possibility that some $p$ levels were missed below 75 keV.

Mechanisms of heavy-ion induced ( $p, n$ )- and ( $n, p$ )-type reactions

M. W. Weisfield, R. A. Williams, and A. A. Caretto, Jr.

Phys. Rev. C 13, 128 (1976) - Published 1 January, 1976

Show Abstract

Excitation functions and recoil ranges for the reactions ${}^{65}{Cu} ({}^{12}C, X) {}^{65}{Zn}$ and ${}^{65}{Cu} ({}^{11}B, X) {}^{65}{Zn}$ were measured for ${}^{12}C$ ion energies between 43 and 122 MeV and for ${}^{12}B$ ion energies between 60 and 115 MeV. The angular distribution for the production of ${}^{65}{Zn}$ by the ${}^{65}{Cu} ({}^{12}C, X) {}^{65}{Zn}$ reaction was determined at 88.6 MeV. The forward projected recoil ranges are not in satisfactory agreement with ranges which would be predicted on the basis of the complete fusion compound nucleus mechanism nor apparently with a simple kinematic treatment of the quasielastic scattering model. The experimental results appear to be consistent with a charge-exchange or nucleon transfer mechanism in which the distance of closest approach varies inversely with incident energy. Evidence for the enhancement of isospin $Δ T = 0$ transitions to target analog states is suggested in that only an upper limit could be placed on the production of cross sections of ${}^{65}{Ni}$ , a $Δ T \neq 0$ product, compared to high yields for ${}^{65}{Zn}$ , a $Δ T = 0$ product.

NUCLEAR REACTIONS ${}^{65}{Cu} ({}^{12}C, X) {}^{65}{Zn}$ , ${}^{65}{Cu} ({}^{12}C, X) {}^{65}{Ni}$ , ${}^{65}{Cu} ({}^{11}B, X) {}^{65}{Zn}$ , ${}^{65}{Cu} ({}^{11}B, X) {}^{65}{Ni}$ ; separated isotope targets, $E ({}^{12}C) = 43 - 122$ MeV, $E ({}^{11}B) = 60 - 115$ MeV; measured $σ (E)$ , recoil fragment ( $E$ ), and fragment $σ (θ)$ for 88.6 MeV ${}^{12}C$ .

Show Abstract

Cross sections for elastic scattering of ${}^{40}{Ar}$ on targets of ${}^{209}{Bi}$ and ${}^{238}U$ were measured at energies of 286 and 340 MeV. Cross sections for the elastic scattering of ${}^{84}{Kr}$ on ${}^{209}{Bi}$ were measured at energies of 600 and 712 MeV. These experimental elastic scattering data were fitted with optical and Fresnel models. The total reaction cross section deduced from the Fresnel model by the one-quarter point technique agrees within a few percent with the result from the optical model. The Fresnel interaction radius and the optical model strong absorption radius are found to be approximately equal and qualitatively reproduced by the sum of the half-density electron scattering radii of the two heavy ions and a constant of 3.2 ± 0.3 fm. A method of estimating total reaction cross sections for heavy ions is presented. Some observations on the real and imaginary potentials of very heavy ions are presented.

Some effects of particle identity in many-body scattering using the method of channel coupling arrays

D. J. Kouri and F. S. Levin

Phys. Rev. C 13, 14 (1976) - Published 1 January, 1976

Show Abstract

Scattering events of the type $a + A \to A + a$ , where $A$ is composed of ( $n - 1$ ) particles all identical to $a$ , are studied within the framework of the channel coupling array approach to many-body scattering. The $n$ coupled equations describing the scattering derived under the assumption that the $n$ particles forming the scattering system are distinguishable, are shown to collapse to a single equation when particle identity is taken into account and a particular choice of a channel coupling array which includes the important special case of channel permuting arrays is made. For this latter choice, which guarantees connectedness, only the exchange Born potential explicitly enters the integral equation for the transition operator or the differential equation for the scattering function. The present derivation provides a justification of equations used previously in $e^{-} + H$ calculations.

NUCLEAR REACTIONS Antisymmetrization effects in the Kouri-Levin-Tobocman coupled channel $T$ operator nuclear reaction formalism are studied for the special case of a particle incident on a target containing $n - 1$ particles identical to the projectile.

Localization in heavy-ion elastic, inelastic, and transfer reactions

P. J. Moffa, C. B. Dover, and J. P. Vary

Phys. Rev. C 13, 147 (1976) - Published 1 January, 1976

Show Abstract

A quantitative technique for studying the localization of heavy-ion reactions in both coordinate ( $r$ ) and angular momentum ( $L$ ) space has been developed. A comparison of the degree of localization in elastic, inelastic, and one-particle transfer reactions is presented. For elastic scattering, the localization is studied as a function of the angular range of the data. A fully quantum mechanical relationship between $L$ and $r$ is demonstrated.
