屏蔽库仑势相移的递推确定
Recursive determination of phase shifts for screened Coulomb potentials
摘要：
在热等离子体原子结构的计算中，连续波函数具有相移的特征，因此相移决定了散射截面。在这篇简短的论文中，我们提出了一个递归关系的相移的情况下，一种特殊类型的参数潜力广泛用于原子结构代码。这些电位必须是静态屏蔽库仑电位（Yukawa型电位）乘以多项式函数的线性组合。
英文摘要：
In the calculation of hot-plasma atomic structure, the continuum wavefunctions are characterized by phase shifts, which therefore determine the scattering cross-sections. In this short paper, we propose a recurrence relation for the phase shifts in the case of a particular type of parametric potentials widely used in atomic-structure codes. These potentials have to be linear combinations of static screened Coulomb potentials (Yukawa-type potentials) multiplied by polynomial functions.
