Abstract:
This tutorial paper presents practical methods for accurately evaluating irregular Coulomb wave functions. Rational approximations to ${G_0}(\eta ,\rho )$ and ${G’_0}(\eta ,\rho )$ are developed along line segments in the $(\eta ,\rho )$ plane to provide useful initial values for the associated differential equation. These approximations, designed for IBM System 360 Fortran double precision, yield results to at least 13 significant decimal places.References
