# I. Generator of determinantal non-relativistic atomic states from spectroscopic notation, computation of matrix elements

## Description

Title of program: TERM Catalogue Id: AAKU_v1_0 Nature of problem The program generates the decomposition of an atomic state into Slater determinants from its description in the usual spectroscopic notation. The output is directly usable by the program EXCGH. The program can also compute matrix elements and reduced matrix elements of operators a~, a+, a^(1/2), Sigma _i<j ... <k (w_i^(1) w_i^(1') ... w_j^(2) w_j^(2') ... w_k^(n)) as well as products of such operators coupled in any way. The results are given in an exact a*square root(b)/c*square root(d) form.
