Simple collective model for nuclear chiral mode

扫码查看
A simple semi-analytical collective model that takes into account the limitations of the variation interval of the collective variable is suggested to describe the chiral dynamics in triaxial odd-odd nuclei with a fixed particle-hole configuration.The collective Hamiltonian is constructed with the potential energy obtained using the postulated ansatz for the wave func-tion symmetric with respect to chiral transformation.By diagonalizing the collective Hamiltonian the wave functions of the lowest states are obtained and the evolution of the energy splitting of the chiral doublets in transition from chiral vibration to chiral rotation regime is demonstrated.
