## Description

Title of program: SOCKITTOME 1 Catalogue Id: AAKA_v1_0 Nature of problem The problem is to obtain wavefunctions for bound atomic levels which permit accurate calculation of energies and transition probabilities. The low-Z Pauli approximation, which is correct to orders Z^3alpha^2 and Z^4alpha^2 in the energy (the non-relativistic energy is of order Z^2) is used to approximate the atomic Hamiltonian. The anti-Hermitian part of those operators characteristic of the Dirac theory is dropped.
