MONTE CARLO CALCULATIONS FOR NEUTRON AND GAMMA PARTICLE INTERACTIONS AND TRANSPORT IN ONE, TWO, AND THREE DIMENSIONAL NUCLEAR ASSEMBLIES--MAGNET IV, PROGRAM FOR ONE AND TWO DIMENSIONAL GEOMETRY, NEUTRON INTERACTIONS, PLAIN SAMPLING

MAGNET IV is designed to attack two basic problems in fast reactor analysis. First, fast reactor criticality, neutron lifetime, isotopic absorption ratios, inelastic scattering by isotopes, leakage spectra, etc., in many region spherical and two dimensional cylindrical geometries. Second, for arbitrary source type, transmission through spherical and cylindrical annuli and absorption and energy loss in such annuli are determined. (W.D.M.)
