Abstract

A comparison is made of the elastic and inelastic scattering of ³H and ³He from ^22,20Ne and ^26,24Mg to look for differences between the collective shapes of protons and neutrons in the target nuclei. Differential cross sections for the scattering of 33.4 MeV ³H and ³He from ²²Ne and ²⁰Ne are measured. Existing data for the scattering of ³H and ³He from ²⁶Mg and ²⁴Mg at around 34 MeV is included in the analysis. The cross sections are analysed by the coupled-channels method on the basis of the collective model and deformed optical model potential fits to the data are obtained. “Satchler's theorem” is used to relate the multipole moments of the deformed potential to the corresponding moments of the nuclear matter. The isospin-dependent nature of the nucleon-nucleon interaction provides the possibility of detecting differences between the moments, and hence distribution, of the target protons and neutrons. Analysis of the dominant rotational states of the target nuclei suggests that the proton distributions are less deformed than the neutron distributions for the ²²Ne and ²⁶Mg nuclei. The deformation lengths and multipole moments from this analysis are compared to other experimental and theoretical results.

Energy levels of light nuclei, A = 20

Supplement to energy levels of A = 21-44 nuclei (VII)
1998, Nuclear Physics A
The experimentally determined properties of A = 21–44 nuclei are compiled and evaluated with special emphasis on nuclear spectroscopy. The present paper, a supplement to the most recent complete A = 21–44 review (90En08), mainly discusses the new data published in the period 1990–1996, and thus can only be used in conjunction with 90En08. The set-up and notation are identical with those of 90En08. Data selection for the supplement, however, is more restricted. Only data are taken along concerning discrete nuclear states with the consequence that papers on reaction mechanisms or on states in the high-energy continuum are disregarded. A novelty in the supplement is the inclusion of a comparison of π = +, T⩽2 states with the shell model (untruncated sd shell).
Elastic scattering of polarized 3He and the 3He optical potential
1993, Nuclear Physics, Section A
The analysing power and differential cross sections of the elastic scattering of ³He by ⁸⁹Y, ^90,91Zr, ^207,208pb and ²⁰⁹Bi have been measured at E_He = 33.3 MeV using a polarized ³He beam. The elastic scattering has been successfully described by phenomenological and “folding” optical-model potentials based on the 3MY nucleon-nucleon interaction. The mass dependence of the spin-orbit part of the optical potential is discussed.
