The program for the transformation of atomic state functions from LS- to jj-coupled basis

Abstract

Here we present the program for the transformation of the expansions of the atomic state functions from LS- to jj-coupled bases. The program is a part of the coupling optimization package Laris and allows to transform the multiconfigurational expansions with the arbitrary number of open shells (including f-electrons) and to identify atomic levels and classify the atomic spectra by means of intermediate quantum numbers of LS- and jj-couplings.
