在核能量密度泛函的框架下，研究了丰中子核的低频集体激发模。结果表明，集体哈密顿方法以Skyrme和成对能量密度泛函为微观输入，定量描述了过渡核中的低激发态.利用沿轴向四极集体坐标的局部简正模计算了大振幅振动和转动的惯性函数。平均场的时间奇数分量完全包含在导数质量中。
Low-frequency collective modes of excitation in neutron-rich nuclei are investigated in the framework of the nuclear energy-density functional method. It is shown that 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. The inertial functions for large-amplitude vibration and rotation are evaluated by the local normal modes along the axial quadrupole collective coordinate. The time-odd components of the mean fields are fully included in the derived masses.
