Abstract The code FGH is an up-dated version of a code COULFG (see [Seaton, Comput. Phys. Comm. 25 (1982) 87]), used for the calculation of the Coulomb functions f and g, analytic in the energy, for attractive potentials. The new code works for attractive and repulsive potentials and also gives the functions h which have simple asymptotic forms. There is an option to use either the variables (ε, r) customary in atomic physics, or (for positive energies) (η, ρ) customary in nuclear physics. When (η, ρ)... Title of program: FGH Catalogue Id: ADQA_v1_0 Nature of problem Coulomb radial functions are required in problems involving interactions between two charged particles. They depend on the scaled variables: angular momentum l; energy epsilon; radial co-ordinate r. For sufficiently small values of r they can be calculated using power-series expansions.
