Pirk: A computer program to calculate the elastic scattering of pions from nuclei

Title of program: PIRK
Catalogue Id: ABCJ_v1_0

Nature of problem
Angular distributions for the elastic scattering of pions from optical potential representations of the nucleus are generated from the partial wave expansion of the scattering amplitude. Complex phase shifts for each partial wave are obtained by numerically integrating the radial Klein-Gordon equation in the interior region and matching to the asymptotic Coulomb wavefunction in the exterior region. The integration is done using the fourth-order Runge-Kutta method. To insure accuracy, the program ...

问题性质
π介子从光学势核表示的弹性散射的角分布是通过散射振幅的部分波展开生成的。通过对每个部分波的径向克莱因-戈尔登方程在内部区域的数值积分，并与外部区域的渐近库仑波函数相匹配，获得每个部分波的复相移。积分采用四阶龙格-库塔法进行。为确保精度，程序..."
