3. DESCRIPTION OF PROGRAM OR FUNCTION -
CEM03.01 is the latest in a series of codes including CEM2k+GEM2, CEM97, and CEM95. It is an extended and improved version of the earlier codes, which implement versions of the Cascade-Exciton Model (CEM) of nuclear reactions. CEM03.01 considers IntraNuclear Cascade (INC), preequilibrium, evaporation, fission, and Fermi Break-up mechanisms of nuclear reactions as well as coalescence of complex particles up to He-4 from fast INC nucleons. CEM03.01 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, He-3, He-4, Pion+, Pion-, and Pion-0. By modifying an input variable, evaporation of as many as 60 isotopes heavier than He-4 (up to Mg-28) may also be modeled. In addition, CEM03.01 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. CEM03.01 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 gamma+A) up to several GeV.

11. HARDWARE REQUIREMENTS - CEM03.01 runs on Sun workstations and Pentium computers.

12. PROGRAMMING LANGUAGE -PSR-0532/01: FORTRAN-77

13. SOFTWARE REQUIREMENTS -
RSICC has tested CEM03.01 under Unix, Windows, and Linux operating systems. The Windows distribution includes an executable created by the code developer with Compaq Visual Fortran Professional Edition 6.6.0 under WindowsXP. This executable also runs under Windows 2000 SP4. The PC Windows version was compiled at RSICC with Intel 9.0 under WindowsXP and with CVF 6.6B under Windows2000.

RSICC tested the Unix version on a Sun workstation running Solaris 9 with the Sun WorkShop 6 update 1 Fortran 77 compiler. RSICC compiled and ran test cases on an AMD Opteron under RedHat Enterprise Linux 4 (2.6.9-22.ELsmp) with The Portland Group, Inc. pgf77 6.0-5 32-bit compiler. This executable is included in the package. Use of a 64-bit computer and a 64-bit compiler will give the closest reproduction of the test cases included with the distribution.
