Abstract A comprehensive package for the calculation of shell-model level densities is presented. A basic combinatorial result. and a sophisticated configuration generator, allow one to obtain exact predictions of the shell model, including the spin distributions in very large configuration spaces, going up to tens to MeV excitation in a heavy nucleus. A simplified pairing interaction, acting only within levels, is also taken into account. Utility programs include standardized generation of single-par... Title of program: SPINDIS Catalogue Id: ADEU_v1_0 Nature of problem The estimation of the final-state level density is an important ingredient in all calculations of reaction rates. Typically, the level density can be measured directly only in narrow windows of energy and spin. The present program efficiently calculates the exact level densities predicted by the shell model up to very high excitation, even in heavy nuclei, and with a simplified pairing interaction taken into account. When fitted to known neutron resonance data, the program provides a benchmark e ...
