摘要: The two-neutron transfer reaction [sup 147]Sm([ital p],[ital t])[sup 145]Sm was studied at [ital E][sub p]]=26 MeV. Angular distributions were measured for [theta][sub lab]=5[degree]--50[degree]. strength of the two neutron monopole pairing phonon[direct product]particle configuration ([ital n][sub [minus]]=1,[ital +]=1)[direct product][nu]2[ital f][sub 7/2] is identified in odd mass and found to be quasi-uniformly spread narrow groups as many 8+5=13 states. This unexpected large fragmentation compared with one core nucleus 144]Sm that from its isotone 143]Nd where vibration less fragmented. couplings other excitation modes are extracted.
