Irreducible angular momentum and spin eigenspaces on atomic subshells

Mathematica implementation of the algorithm described in the paper Efficient algorithm for many-electron angular momentum and spin diagonalization on atomic subshells, see Ref. 1 below.

The main code resides in the Mathematica package irredLSbase.m, and the computations are performed in the notebook irredLS.nb. This notebook requires the FermiFab toolbox (see Ref. 2) and stores the results in irredLS.m.

The files fermi2latex.m and irredLSlatex.nb generate the Latex tables of the eigenspaces in the tables subfolder.
