# Coulomb functions in entire (ɳ, ϱ) - plane

## Description

Title of program: COULOM FOR REAL ENERGY Catalogue Id: ABOQ_v1_0 Nature of problem The subroutine COULOM calculates the regular and irregular Coulomb functions Fl(eta,rho) and Gl(eta,rho) and their derivatives for real positive energy in the whole (eta,rho)-plane (eta can take all values between and equal to -500 and 500, rho is greater than or equal to 0) with a uniformly high accuracy. This program will be useful, e.g., for the nuclear scattering and reaction calculations involving heavy projectiles, when rho is no longer very large compared with eta. It thus supplements exi ...
