Abstract

Formulae for the first-order electrostatic interaction between configurations up to four open shells (see Part I in Eur. Phys. J. Plus 130, 14 (2015)) are presented. They form the basis for the design of an efficient computer package allowing large-scale calculations of fine and hyperfine structure and predict spectral line strengths of complex atoms.
