# A program for the complete expansion of jj-coupled symmetry functions into Slater determinants

## Description

Abstract Different applications of atomic structure theory favour different representations of the many-electron wave function. For an estimate of energy levels it is appropriate to start from symmetry adapted functions which keep the size of the Hamiltonian matrix to be diagonalized small. In the calculation of transition properties, on the other hand, the electron rearrangement during an atomic excitation or decay process can be effectively treated, if the wave functions are represented as linear co...
