Show Abstract

The experimental data for pion threshold photoproduction from nucleons are examined and are used to distinguish between models used to calculate pion-exchange currents in nuclei. The roles of the equivalence theorem and equiva ence-breaking terms are stressed in both types of processes.

Coupled-channel method for nuclear scattering of Dirac particles: High-energy electrons on calcium

Robert L. Mercer

Phys. Rev. C 15, 1786 (1977) - Published 1 May, 1977

Show Abstract

We obtain a solution of the Dirac equation in the presence of the electromagnetic field of a complex nucleus by means of coupled-channel partial wave analysis using a new method in which the asymptotic solutions of the coupled radial wave equations include all electromagnetic couplings. A compu er program employing this method is used to determine the importance of dispersion effects in the scattering of 250 MeV electrons from ${}^{40}{Ca}$ and ${}^{44}{Ca}$ . We find the dispersion effects to be less than 1% for angles below 90° (i.e., considerably less than experimental error over the range investigated experimentally), thus supporting the view that the difference in the differential cross sections from ${}^{40}{Ca}$ and ${}^{44}{Ca}$ arises primarily from a difference in the ground state charge distributions of the two isotopes.

Show Abstract

We have measured the $4 f \to 3 d$ pionic x-ray transitions in ${}^{148}{Nd}$ and ${}^{150}{Nd}$ in order to determine the strong interaction effect between the pion and these nuclei. The measured transition energies and broadenings of these and all previously measured isotopes, which have appreciably strong interaction effects in the $3 d$ level, were fitted by an optical potential. The isotope shift of the pionic x rays between ${}^{150}{Nd}$ - ${}^{148}{Nd}$ was consistent with a change in neutron radius of 45±48 am. The sensitivity of this determination of the change in neutron radius on the assumed form of the neutron distribution is discussed.

Population of $0^{+}$ states in ${}^{126}{Te}$ by decay of ${}^{126}I$ and $γ$ softness in even-even Te nuclei

S. V. Jackson and R. A. Meyer

Phys. Rev. C 15, 1806 (1977) - Published 1 May, 1977

Show Abstract

The unique, first-forbidden $β$ decay of ${}^{126}I$ with $J^{π} = 2^{-}$ to the known $0^{+}$ level at 1873 keV in ${}^{126}{Te}$ has been observed for the first time. The associated $log f_{1} t$ value is 10.1. This value is consistent with the decay of other isomers of iodine with $J^{π}$ of $2^{-}$ . In contrast to previous work, no evidence is found for other $0^{+}$ levels in ${}^{126}{Te}$ below 2 MeV. A decay scheme for the $β^{-}$ and $\frac{β^{+}}{EC}$ decay of ${}^{126}I$ is presented. The level properties of the even-even Te nuclei are discussed within the framework of a nuclear potential having softness in the $γ$ direction.

Show Abstract

${}_{33}^{68}{As}_{35}$ was produced by the ${}^{58}{Ni} ({}^{12}C, p n) {}^{68}{As}$ reaction at $E_{{}^{12}C} = 32 and 42$ MeV. $γ$ rays from the decay of ${}^{68}{As}$ were observed both in singles and coincidence using large Ge(Li) detectors. This work yielded a more accurate half-life for ${}^{68}{As}$ (151.5 ± 0.9 sec) as well as the identification of several new levels in ${}^{68}{Ge}$ , including a low-lying $0^{+}$ state. The ground-state spin of ${}^{68}{As}$ was determined to be $3^{(+)}$ and its total decay energy $Q_{EC}$ was measured to be 8.1 ± 0.1 MeV. This corresponds to a mass excess of -58.9 ± 0.1 MeV, which is compared with various predictions. Assignments or restrictions of the spin and parity for many states observed in ${}^{68}{Ge}$ have been made. The structure of ${}^{68}{Ge}$ is discussed in terms of a vibrational model.

Show Abstract

A total of 142 $γ$ rays were observed in the decay of the 45- and 85-sec isomers of ${}^{136}I$ using an on-line isotope separator system. Of these, 116 were placed in a level scheme for ${}^{136}{Xe}$ consisting of 50 excited levels up to 6624 keV using results from Ge(Li) $γ$ singles and $γ γ$ -coincidence measurements. Our results are compared with results from earlier decay and reaction experiments, and the levels below 2.8 MeV are compared with predictions of recent shell-model calculations. Strong $β$ population was observed to states above 3.5 MeV which are interpreted as neutron particle-hole states.

Phys. Rev. C 15, 1835 (1977) - Published 1 May, 1977

Show Abstract

The particle decay of the ground state of ${}^{6}{Be}$ was observed following population in the ${}^{6}{Li} ({}^{3}{He}, t) {}^{6}{Be}$ reaction. The $α$ particle decay spectrum corresponds to the ordinary three body phase space shape for energies above about 100 keV in the ${}^{6}{Be}$ center-of-mass system. At lower energies the relative yield exceeds the available phase space. It is shown that neither the phase space spectrum modified by the proton-proton final state interaction nor the spectrum corresponding to sequential decay through the ${}^{5}{Li}$ ground state have shapes consistent with the data. The enhanced yield of low energy $α$ particles is not accounted for by either process.

Show Abstract

$γ - γ$ directional correlation studies have been carried out on the (1063.62-569.67) keV $\frac{13}{2^{+}} \overset{M 4 + E 5}{\to} \frac{5}{2^{-}} \overset{E 2}{\to} \frac{1}{2^{-}}$ cascade in the decay of ${}^{207}{Bi}$ using the time differential perturbed angular correlation method. The measurements show time dependent magnetic perturbation of the correlation. From the plot of $A_{2} (\bar{t})$ vs $\bar{t}$ (finite time resolution corrected), the value of the relaxation parameter $λ_{2}$ and the unperturbed $A_{0} (t)$ coefficient (solid angle corrected) obtained are (2.4 ± 0.3) × $10^{9}$ $\sec^{- 1}$ and 0.259 ± 0.016, respectively. From the plot of $A_{0} (t)$ vs $t$ , the unperturbed value of $T_{\frac{1}{2}}$ and therefrom $λ_{0}$ for the 569.67 keV level are determined to be (130.7 ± 1.3) ps and (5.30 ± 0.06) × $10^{9}$ $\sec^{- 1}$ , respectively. Using the $λ_{0}$ and $λ_{2}$ values, the integral attenuation coefficient ${\bar{G}}_{2} (\propto)$ has been estimated to be 0.69 ± 0.03. The differential data at various angles were integrated and the solid angle corrected $A_{2} (\infty)$ coefficient thus obtained is 0.204 ± 0.005. The perturbation mechanism is discussed in the light of the spin-spin interactions between the $6 s$ electrons of the neighboring paramagnetic ${Pb}^{+ + +}$ ions. The results are found to be consistent with the theory of Abragam and Pound.

Dispersion energies and excitation parameters in fermion fluids

C. W. Wong

Phys. Rev. C 15, 1866 (1977) - Published 1 May, 1977

Show Abstract

Certain physical mechanisms contributing to the Brueckner pair dispersion energy $W_{2}^{D}$ are reviewed. This $W_{2}^{D}$ is found to appear also in the Iwamoto-Yamada cluster expansion if the same Brueckner state- and momentum-dependent correlation operators are used. It does not appear in the two-body Iwamoto-Yamada energy, however, but in the three-body energy. Up to this point, a Brueckner triplet dispersion energy $W_{3}^{D}$ has not yet appeared. This $W_{3}^{D}$ depends on a triplet excitation parameter $κ_{3}$ , which is calculated using Jastrow correlation functions. We find that $κ_{3}$ is small when $κ_{2}$ is small (≲ 0.1), and large when $κ_{2}$ is large (≳ 0.4). Since $κ_{2} \approx 0.2$ in nuclear matter, there is hope that both Brueckner and Iwamoto-Yamada expansions converge to the same answer at fairly low orders.

Even-parity states of ${}^{95}{Tc}$

L. D. Skouras and C. Dedes

Phys. Rev. C 15, 1873 (1977) - Published 1 May, 1977

Show Abstract

An attempt is made to explain the observed even-parity spectrum and transition rates of ${}^{95}{Tc}$ . The shell-model approach is followed and the three valence protons are restricted to the $0 g_{\frac{9}{2}}$ orbital. On the other hand, full configuration mixing has been assumed for the two valence neutrons which are allowed to take all possible values in the $1 d_{\frac{5}{2}}$ , $2 s_{\frac{1}{2}}$ , $1 d_{\frac{3}{2}}$ , and $0 g_{\frac{7}{2}}$ orbitals. Experimental single particle energies are used in the calculation while the two-body matrix elements are derived from the Sussex and Yale interactions by means of second order perturbation theory. Thus, using only one free parameter, namely the effective charge, we have reproduced to a good approximation the excitation energies and transition rates of about 35 observed levels. In addition, the calculation predicts a number of levels that, quite possibly, have not yet been experimentally observed.

Show Abstract

A brief review of the development of $α$ -decay-rate theory is given. Then in this paper are presented relative $α$ decay-rate theoretical calculations for doubly odd spherical nuclei for ${}^{212}{At}$ and ${}^{212}{At}^{m}$ $α$ decay to excited states of ${}^{208}{Bi}$ using mixed-configuration-shell-model parent and daughter wave functions and $α$ particle approximations. Results are presented for no mixing and for Kim and Rasmussen, Ma and True, and Kuo and Herling wave functions for both the parent and daughter nucleus. The results are compared with the experimental data. There is a great sensitivity to configuration mixing, and no set of wave functions is wholly satisfactory. Stripping and pickup experiments testing the wave functions are reviewed and difficulties noted. It is concluded that $α$ -decay rates provide a stringent test for the effective shell-model neutron-proton interaction in the lead region. Further theoretical and experimental work is needed.

Deuteron quadrupole moment and energy dependence of the nucleon-nucleon interaction

N. J. McGurk

Phys. Rev. C 15, 1924 (1977) - Published 1 May, 1977

Show Abstract

In the single-nucleon approximation model, the recent experimental value for the quadrupole moment of the deuteron is shown to be too large a quantity to be fitted by energy-independent nucleon-nucleon interactions that yield the experiment values of the triplet scattering length and deuteron binding energy with sufficient precision. The introduction of energy dependence into the nucleon-nucleon interaction loosens the restrictiveness of the shape-independent approximation. This then allows a fit to the deuteron quadrupole moment in the single-nucleon approximation with simultaneous fits to the experimental values of the triplet scattering length and deuteron energy. We argue the necessity of ∼10% corrections to the deuteron asymptotic normalization due to energy dependence. Alternatively, we have to consider corrections to the single-nucleon model from intermediate-state current diagrams, such as the "pair" current, and also meson degrees of freedom, to compensate for the deficiency.
