Title of program: KLEIN: COULOMB WFN, REAL L,ETA,X Catalogue Id: ABNJ_v1_0 Nature of problem KLEIN computes relativistic Schrodinger (Klein-Gordon) equation solutions, i.e. Coulomb functions for real lambda > - 1, F lambda (eta,x), G lambda (eta,x), F'lambda (eta,x) and G'lambda (eta,x) for real x > 0 and real eta, -10^4 < eta < 10^4. Hence it is also suitable for Bessel and spherical Bessel functions. Accuracies are in the range 10^-14 -10^-16 in oscillating region, and approximately 10^-30 on an extended precision compiler. The program is suitable for generating Klein-Gordon wave ...
