Shell model description of correlations in Ni-56 and Sn-100

摘要

Through a set of large scale shell model calculations, we illustrate the influence of correlations on several basic observables. In the Ni-56 region (fp shell), and the Sn-100 region (gds shell) we start from a single particle picture, the valence space is enlarged and eigenstates energies, electromagnetic rates are studied as a function of particle-hole excitations. Very similar behaviour is expected for the nature of Sn-100 and Ni-56. [References: 10]
