The structure of neutron-rich calcium isotopes studied by the shell model with realistic effective interactions

摘要: We study the structure of neutron-rich calcium isotopes in shell model with realistic interactions. The CD-Bonn and Kuo-Brown (KB) interactions are used. As these do not include three-body force, their direct use leads to poor results. tested whether adjustment single particle energies (SPEs) would be sufficient correlations empirically. It turns out that interaction, after SPEs, gives good agreement experimental data for spectroscopy. For KB both SPEs monopole terms require adjustments. Thus, problem is less serious modern which perturbations up third order. also effect non-central force on structure. found tensor interaction weaker than interaction.
