Abstract : The statistical model assumes a statistical distribution of nuclear density levels in the decay of the compound nucleus. The densities of nuclear levels can be described by a standard formula in a region containing many energy levels. This formula can be used to predict the cross-sections for photonuclear reactions within the energy range 0 to 30 MEV. Provided assumptions are made neglecting the coulomb effect, spin, parity, angular momentum, and tertiary and higher order reactions, these predictions can be made by a digital computer and the results plotted on a graph with experimental data for comparison. The digital computer program is used to find the statistical level density formula that most closely approximates the cross-sections obtained experimentally. (Author)
