SKYRME ENERGY-DENSITY FUNCTIONAL APPROACH TO COLLECTIVE MODES OF EXCITATION IN EXOTIC NUCLEI

摘要

Our recent developments for the microscopic description of nuclear collective dynamics in the framework of the time-dependent density functional theory is presented. We show two examples; one is for small-amplitude collective dynamics and the other for the large-amplitude collective dynamics. First, it is shown that the quasiparticle random-phase approximation is ready for the systematic investigation of the giant resonances in the entire mass region of nuclear chart. Secondly, we show that the shape-phase transition investigated by employing the collective Hamiltonian approach gives the quantitative description of the low-lying states in transitional nuclei with the Skyrme and pairing energy density functionals as a microscopic input.
