The Shell-Model Code NuShellX@MSU

NuShellX is a set of computer codes written by Bill Rae [1] that are used to obtain exact energies, eigenvectors and spectrosopic overlaps for low-lying states in shellmodel Hamiltonian matrix calculations with very large basis dimensions It uses a J-coupled proton-neutron basis, and J-scheme matrix dimensions of up to the order of 100 million can be considered. NuShellX@MSU is a set of wrapper codes written by Alex Brown [2] that use data files for model spaces and Hamiltonians to generate input for NuShellX. The wrapper codes also convert the NuShellX output into figures and tables for energy levels, gamma decay and beta decay.
