RCPL1 calculates detailed Doppler-broadened neutron resonance cross sections from unresolved and either single-level or multilevel resolved resonance parameters, for any number of nuclides, within an arbitrary energy structure consisting of up to 99 epithermal groups and one thermal group. The highest energy groups are divided into as many as 500 energy intervals for resonance cross section detail. These groups also allow inelastic scattering, expressed through group-wise transfer matrices, for the resonance nuclides and for any number of additional nuclides without detailed resonance descriptions. Subsequent epithermal groups may be subdivided into 1000 intervals, and the thermal group may contain 299 intervals. Elastic scattering for each nuclide is described by the first four components of the differential scattering cross section in the CM system, and the thermal group will treat two P3 scattering kernels through thermal subgroup transfer matrices. RCPL1 also calculates Compton, photoelectric, and pair production cross sections for photon interactions with any number of nuclides, and the gamma emission spectra from these nuclides are tabulated. The arbitrary energy group structure consists of up to 100 groups, each divided into as many as 400 intervals.CDC7600,6600; FORTRAN IV (99%) and COMPASS (1%); SCOPE 1.1 (CDC7600), SCOPE 3.3, 3.4 (CDC6600); CDC7600 or CDC6600 with variable requirement of large core memory (LCM) or extended core storage (ECS).
