NUMER, a code for Numerov integrations of Coulomb functions. (English)
[J] Comput. Phys. Commun. 146, No.2, 254-260 (2002). ISSN 0010-4655

Summary: 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 $(\varepsilon,r)$ or the nuclear-physics variables $(\eta,\rho)$.
