基于绝热自洽集体坐标（ASCC）方法，在微观上计算了集体惯性质量系数，并沿着集体反应路径自洽地确定了集体惯性质量系数随平动、相对转动和转动的变化规律.研究了平均场势的奇时分量对惯性质量的影响。并将计算结果与用起动公式计算的结果进行了比较。基于ASCC方法的惯性质量再现了平移运动的精确核总质量以及相对和旋转运动的精确约化质量作为渐近值。相比之下，曲柄公式不能做到这一点。这是由于ASCC方法中正确恢复了（局部）伽利略不变性，但在曲柄公式中违反了这一事实。用微观导出的势和惯性质量构造了低能核反应的模型哈密顿量。计算了天体物理因子，说明了本征惯性质量微观计算的重要性。
Collective inertial mass coefficients with respect to translational, relative, and rotational motions are microscopically calculated, along the collective reaction path self-consistently determined, based on the adiabatic self-consistent collective coordinate (ASCC) method. The impact of the time-odd component of the mean-field potential on the inertial masses are investigated. The results are compared with those calculated with the cranking formulas. The inertial masses based on the ASCC method reproduce the exact total nuclear mass for the translational motion as well as the exact reduced masses as the asymptotic values for the relative and rotational motions. In contrast, the cranking formulas fail to do so. This is due to the fact that the (local) Galilean invariance is properly restored in the ASCC method but violated in the cranking formulas. A model Hamiltonian for low-energy nuclear reaction is constructed with the microscopically derived potentials and inertial masses. The astrophysicalfactors are calculated, which indicates the importance of microscopic calculation of proper inertial masses.
