Introduction

The function of this program is to compute all possible radial integrals and combined with the angular data to determine all requested contributions to the Hamiltonian. All contributions are grouped into three types of data, which are saved in three files, respectively:
  1. hnr.lst non-relativistic, J-independent contributions.
  2. hzeta.lst spin-orbit and spin-other-orbit contributions
  3. hspin.lst spin-spin contributions
This stage of the Breit-Pauli calculation was made a separate program in order to simplify the process of energy adjustment of computed eigenvalues, which is the last step bp_eiv in a Breit-Pauli calculation.

The basic constants of the program are initialized in inita(), initr(). Then the user is prompted to input information about the name of the files with configuration .c and radial .w data. The user also need to specify the type of calculation, relativistic, with or without mass correction and the type of integration: in Gradient or Slater form.
