# Radial integrals in the Coulomb-Born approximation

## Description

Abstract This paper describes a computer program package CRADINTEG which evaluates the radial integrals for the monopole and dipole terms in the Coulomb-Born calculation of the excitation of positive ions by electron impact. The integrals are expressed in terms of hypergeometric functions, which are numerically obtained. Title of program: CRADINTEG Catalogue Id: ADAD_v1_0 Nature of problem This program calculates radial integrals in the Coulomb-Born calculation of the excitation of positive ions by electron impact. The integral is defined as an integral of the multipolar interaction over the initial and final Coulomb scattering functions.
