Abstract

The strength function of the d5/2 hole state in Ca39 has been determined from the (p,d) reaction at 65 MeV. The d5/2 hole state consists of three strongly excited states at the excitation energies of 56 MeV with strengths of 41% of the sum-rule limit and a group of several tens of weakly excited states instead of six or seven peaks as in previous data, distributed in the excitation energy region from 6 to 10 MeV with 38% of the sum-rule limit. This is evidence for the general feature of the fragmentation of deeply bound hole states, proved by peak-by-peak analysis. The strength quenching of the stretched 6- state in Ca40(p,n) reaction is discussed with the strength fragmentation of the d5/2 hole state.
