Two-program package to calculate the ground and excited state wave functions in the Hartree—Fock—Dirac approximation
Description
Abstract Algorithms and computer codes to calculate the ground and excited (discrete and continuum) state wave functions of many-electron atoms and ions, including those containing positive/negative muons, in the Hartree—Fock—Dirac (HFD) approximation are reported. In contrast to the usual technique, the system of 2S self-consistent first order integro-differential equations of the HFD is solved by reducing it first to a system of S second order ones. The latter is then treated numerically by means of...
