Nuclear structure studies by the 62–64Ni(d, p) reaction

Abstract

Levels of 63 Ni and 65 Ni below 5 MeV have been studied by observation of the energy and angular distribution of protons emitted in the 62–64 Ni(d,p) reactions. For many levels, l -values of the captured neutrons have been assigned by comparison of the angular distribution with calculations based on the DWBA. These comparisons yield the spectroscopic factors. A sum rule analysis is made and the results are compared with the predictions of the strong-pairing and shell models. The positions of the single quasiparticle states determined have been used as input for an IGE calculation to obtain the force parameters.
