Symbolic algorithms for the computation of Moshinsky brackets and nuclear matrix elements

To facilitate the use of the extended nuclear shell model (NSM), a F ERMI module for calculating some of its basic quantities in the framework of MAPLE is provided. The Moshinsky brackets, the matrix elements for several central and non-central interactions between nuclear two-particle states as well as their expansion in terms of Talmi integrals are easily given within a symbolic formulation. All of these quantities are available for interactive work. Program summary
