A Fortran program to calculate the matrix elements of the Coulomb interaction involving hydrogenic wave functions

The program MTRXCOUL calculates the matrix elements of the Coulomb interaction between a charged particle and an atomic electron. Bound-free transitions are considered, and non-relativistic hydrogenic wave functions are used. In this revised version a bug discovered in the F3Y CPC Program Library (PL) subprogram is fixed. Furthermore, the COULCC CPC PL subprogram applied for the calculations of the radial wave functions of the free states and the Bessel functions is replaced by the CPC PL subprogram DCOUL. The previous version of this program (ADMW_v1_0) may be found at http://dx.doi.org/10.1016/S0010-4655(00)00160-0.
