摘要
The effect of the two-nucleon excitation from p to sd shell is discussed on12 C and14C in the frame work of the nuclear shell model. The recently suggested shell-model Hamiltonian YSOX provides an suitable tool to investigate the 2hω excitation in psd region. Because the strength of the< pp|V |sdsd > interaction, which represents the interaction between the 0 and 2hω configurations, is considered in the construction of the Hamiltonian YSOX. The level of12 C is almost independent on the < pp|V |sdsd > interaction, but excitation energies of certain states in14 C are strongly affected by it.Further investigation shows that the percentage of 2hω configuration in these states is quite different from that of the ground state. The non-linear effects of the < pp|V |sdsd > interaction on the configurations and transition rates are also discussed.
The effect of the two-nucleon excitation from p to sd shell is discussed on 12C and 14C in the frame work of the nuclear shell model. The recently suggested shell-model Hamiltonian YSOX provides an suitable tool to investigate the 2 hw excitation in psd region. Because the strength of the 〈 pp|V|sdsd 〉 interaction, which represents the interaction between the 0 and 2 hw configurations, is considered in the construction of the Hamiltonian YSOX. The level of 12C is almost independent on the 〈 pplVIsdsd 〉 interaction, but excitation energies of certain states in 14C are strongly affected by it Further investigation shows that the percentage of 2 hw configuration in these states is quite different from that of the ground state. The non-linear effects of the 〈 pplVIsdsd 〉 interaction on the configurations and transition rates are also discussed.
