我们讨论了四个处方评估集体质量参数适合平移,旋转和大幅度集体运动。这两种方法分别是绝热含时Hartree-Fock理论(ATDHF)和生成坐标法(GCM),它们都有曲率修正和没有曲率修正。作为实际例子,我们考虑了16 O +16 O碰撞,采用了最近发展的直接Yukawa和Coulomb项的密度相关相互作用。本文提出了一种快速迭代格式,用于求解三维坐标或动量空间网格中的线性响应方程。作为测试用例,我们考虑了重离子之间的各种距离的旋转和平移惯性参数。我们发现,曲率修正是可以忽略不计的,而ATDHF和GCM之间的差异可能会达到约35%的情况下,旋转。
We discuss four prescriptions for evaluating a collective mass parameter suitable for translations, rotations and large amplitude collective motions. These are the adiabatic time dependent Hartree-Fock theory (ATDHF) and the generator coordinate method (GCM), both with and without curvature corrections. As practical example we consider the16O+16O collision using a recently developed density dependent interaction with direct Yukawa and Coulomb terms. We present a fast iteration scheme for solving the linear response equation in a three-dimensional coordinate or momentum space grid. As test cases we consider the rotational and translational inertia parameters for various distances between the heavy ions. We find that curvature corrections are negligible whereas the difference between ATDHF and GCM may amount to about 35% in case of rotation.
