DWPI: A computer program to calculate the inelastic scattering of pions from nuclei

Title of program: DWPI
Catalogue Id: ABIG_v1_0

Nature of problem
Angular distributions for the inelastic scattering of pions are generated using the distorted wave impulse approximation (DWIA). The cross-section for a given transition is calculated by summing a partial wave expansion. The T-matrix elements are calculated using distorted pion waves from the program PIRK, and therefore include elastic scattering to all orders. The excitation is treated in first order only. Several optical potentials and nuclear densities are available in the program. The transi ...

问题性质
π介子非弹性散射的角分布系采用畸变波脉冲近似法（DWIA）生成。给定跃迁的截面通过求和部分波展开计算得出。T矩阵的元素通过使用来自程序PIRK的畸变π介子波计算，因此包含所有阶数的弹性散射。激发仅在一阶进行处理。程序中提供了多种光学势和核密度。该转换涉及...
