Good Agreement

A high resolution study of γ-ray transitions in 143Sm following the β+ decay of 143Eu has been made using Ge(Li) detectors. Fifty-seven γ rays are assigned to the decay of 143Eu, and the ground state spin of 143Eu is established as 5/2+. Spin and parity assignments are made on the basis of γ-ray branching, deduced log ft values, and by comparison with previous (p,d) reaction data. Good agreement between experiment and predictions of the intermediate coupling model suggests that this model adequately accounts for the low lying levels of 143Sm.

Intermediate Coupling Model

In recent years the nucleus 51 Y has been extensively studied, both experimentally by Horoshko et al. (1970), using the 48Ti(oc, py)51y reaction, and theoretically in terms of shell model calculations by many authors (McCullen et al. 1964; Horoshko et al. 1970; Lips and McEllistrem 1970). Mixed configuration shell model calculations by Lips and McEllistrem, in particular, have successfully reproduced the low-lying energy levels of5ly. However, strong coupling rotational model calculations by Malik and Scholz (1966) did not give satisfactory results. In the present work, the intermediate coupling unified model (Bohr and Mottelson 1953; Choudhury 1954) is applied to Sly. The purpose of this work is to show that the intermediate coupling model can successfully predict the low-lying energy levels of Sly.

Parameter Values

The positive parity energy spectra of 29Si, 31P, and 35Cl are calculated in terms of a modified intermediate-coupling model. The vibrating cores are assumed to be 28Si, 32S, and 36Ar respectively, with the 1d3/2, 2s1/2, and 1d5/2 orbits available to particle and hole states. Account is taken of the anharmonicity of the two-phonon core states. The calculated energy spectra and decay schemes are in agreement with recent experimental results with parameter values consistent with previous studies in the s–d shell.

Quadrupole Term

The level structures of the nuclei 63Cu, 69Ga, 75As, 79Br, 83Rb, and 89Y are investigated in the framework of the unified model.Each nucleus is considered to consist of an even–even vibrating core and extra-core proton quasiparticle. The quasiparticle–core interaction Hamiltonian is assumed to be given by a dipole plus a quadrupole term. The coupling of a g9/2 state to the vibrating core leads to the formation of states of positive parity with [Formula: see text]. Such states with I up to 11/2+ have been recently observed in the nuclei under investigation. In the case of negative parity states the extra core proton quasiparticle is assumed to have available the p3/2, p1/2, and ƒ5/2 states. Many features of the investigated nuclei are explained by the model at least qualitatively. The present calculations do not exhaust the possibility of improved results. Future experimental data will be highly desirable not only for testing but also for improving the model.

Intermediate Coupling Model

The 6.48-Mev level of C11 has been studied by means of the B10(d,nγ)C11 reaction using time-of-flight techniques. The results show that the ratio of the ground-state transition to the cascade via the second excited state of C11 is 8 ± 1:1. Comparison is made with the predictions of the intermediate-coupling model.
