Probing Transitional Regions with Nuclear Transfer Reactions

摘要

Experimental probes which may provide ways to assess differences between presently competing theories for transitional nuclei are of great current interest. In this paper one-neutron transfer data for sub 52 Te nuclei and one-proton transfer data for a long chain of sub 61 Pm nuclei are discussed, with special emphasis on what may be learned from cross sections for weakly excited high- spin states with the parity of the intruding h(sub 11/2) orbitals in these regions. The data for the Pm nuclei covers the full range from the closed N=82 shell to the good rotors (N=92) and exhibits how the proton spectrum responds to increasing the neutron number of the system. The population of the states is discussed within the framework of the coupled-channels-Born-approximation (CCBA), including a critical evaluation of current recipes for calculation of transfer and scattering form factors.
