A program for calculating Regge trajectories in potential scattering

Title of program: REGGE TRAJECTORY
Catalogue Id: AAGA_v1_0

Nature of problem
This program solves the radial Schrodinger equation and finds the positions and residues of Regge poles for a Yukawa potential and follows these poles automatically as a function of energy. Alternatively, it will compute the S-matrix and phase shifts at a specified grid of points in the complex angular momentum plane and for a given set of energies. The program can be modified to calculate Regge trajectories for any potential which can be specified by an analytic formula.

程序标题：REGGE 轨迹

目录编号：AAGA_v1_0

问题性质
本程序求解径向薛定谔方程，并针对 Yukawa 势找出 Regge 极的位置和留数，同时自动跟踪这些极随能量的变化。或者，该程序能够在复角动量平面上的指定网格点以及给定的能量集中计算 S 矩阵和相移。通过修改程序，可计算由解析公式指定的任何势能的 Regge 轨迹。
