COMPARISON OF TWO-NEUTRON TRANSFER INTENSITIES IN RARE EARTH NUCLEI WITH PREDICTIONS OF MICROSCOPIC MODELS

The microscopic structure of 0+ states in well-deformed even-even nuclei was generated within a framework of exact diagonalization of the residual pairing and n−p forces in a seniority-zero Nilsson orbital basis. Available experimental results on the fraction of the L=0 two-neutron transfer intensity which goes to excited 0+ states are compared with microscopic model calculations, giving good overall agreement. Some prominent features of the experimental systematics appear to depend on details of the single-particle states, and are therefore better explained with a microscopic description than with the IBM.
