## Description

Title of program: COUL Catalogue Id: AANB_v1_0 Nature of problem The routine COUL calculates the exponentially decaying Whittaker functions V_L(c, x) and their radial derivatives, where c = square root (-k^2)/Z and x = Zr, for real negative energy k^2 and for all (c, x). It is well suited for all programs which require matching to asymptotic Coulomb wave functions in atomic physics. Versions of this program held in the CPC repository in Mendeley Data AANB_v1_0; COUL; 10.1016/0010-4655(80)90022-3 This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2019)
