Abstract The code numer is used for numerical integrations of Coulomb radial wave functions using the Numerov method. The input specifies a function and its derivative to start integrations, an integration range and an accuracy parameter ac such that the accumulated error is no larger than ac. Alternative input is initial function, integration step, and function after first step. For positive energies, options exist to use either the atomic-physics variables (ϵ,r) or the nuclear-physics variables (η,ρ... Title of program: NUMER Catalogue Id: ADQB_v1_0 Nature of problem Coulomb radial functions are required in problems involving interactions between two charged particles. They depend on scaled variables: angular momentum l; energy epsilon; radial co-ordinate r. Given either: a Coulomb function and its derivative at one value of r and an accuracy parameter, or an interval h = deltar, a function at two values of r separated by h; the code calculates the function for a specified range of r values [1].
