/sup 74/Ge(p,. cap alpha. )/sup 71/Ga reaction at 36. 25 MeV

Journal Article · · Phys. Rev. C; (United States)
The /sup 74/Ge(p,..cap alpha..)/sup 71/Ga reaction has been studied at 36.25 MeV bombarding energy. Angular distributions of alpha particles were recorded and analyzed with distorted-wave Born approximation theory and a totally microscopic form factor for the three-particle transfers. Theoretical calculations in a restricted shell-model space using a modified surface delta interaction reproduce fairly well the /sup 71/Ga excitation energies and the observed strengths in (d,/sup 3/He) and (p,..cap alpha..) spectra, with the exception of the (p,..cap alpha..) ground state transition. This disagreement confirms the anomalies observed by (d,/sup 3/He) reactions, in the occupation numbers Z = 32 and between N = 40 and 42, which can be related to changes in the nuclear shape.
