## Description

Title of program: ATOMINT Catalogue Id: ACRO_v1_0 Nature of problem The subroutine ATOMINT evaluates an atomic integral, containing 3 odd powers of interelectronic separation coordinates, which appears in bound state variational calculations of three electron atoms, and in phase shift variational calculation of scattering of electron (or positrons) by two electron atoms. Versions of this program held in the CPC repository in Mendeley Data ACRO_v1_0; ATOMINT; 10.1016/0010-4655(73)90055-6 This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2019)
