The Fortran 77 code CEM03.03 is an extended and improved version of the earlier codes CEM03.01 and CEM2k+GEM2, which are based in turn on their predecessor codes CEM2k, CEM97, CEM95, CEM92M, CEM92, and MARIAG, which implement versions of the Cascade- Exciton Model (CEM) of nuclear reactions. CEM03.03 calculates total reaction and fission cross-sections, nuclear fissilities, excitation functions, nuclide distributions (yields) of all produced isotopes separately as well as their A- and Z-distributions, energy and angular spectra, double-differential cross-sections, mean multiplicities, i.e. the number of ejectiles per inelastic interaction of the projectile with the target, ejectile yields and their mean energies for n, p, d, t, 3He, 4He, π+, π−, and πO. In addition, CEM03.03 provides in its output separately the yields of Forward (F) and Backward (B) produced isotopes, their mean kinetic energies, A and Z-distributions of the mean emission angle, their parallel velocities, and the F/B ratio of all products in the laboratory system, distributions of the mean angle between two fission fragments, of neutron multiplicity, of the excitation energy, of momentum and angular momentum, and of mass and charge numbers of residual nuclei after the INC and preequilibrium stages of reactions, as well as for fissioning nuclei before and after fission. CEM03.03 calculates reactions induced by nucleons, pions, bremsstrahlung and monochromatic photons on not too light targets at incident energies from ∼10 MeV (∼ 30 MeV, in the case of γ+A) up to several GeV. This Manual describes the basic assumptions of the improved CEM as realized in the code CEM03.03, essential technical details of the code such as the description of the input and output files, and provides the user with necessary information for practical use of and for possible modification of the CEM03.03 output, if required.
A Fortran 77 compatible compiler is required. CEM03.03 has been tested at RSICC under Unix, Windows, and Linux operating systems. RSICC compiled and ran test cases on an AMD Opteron under RedHat Enterprise Linux with The Portland Group, Inc. pgf90 7.2.2 64-bit compiler and Intel ifort 12.0.2 64-bit compiler. Use of a 64-bit computer and a 64-bit compiler will give the closest reproduction of the test cases included with the distribution.
