3. DESCRIPTION OF PROGRAM OR FUNCTION
LAHET2.8 is typically used for transport calculation for nucleons and pions in the medium energy range within a complex geometry. Results estimated include particle fluxes, particle production, energy deposition, activation and material damage. LAHET may also be used to calculate differential particle production cross sections from the models included in the code.

4. METHODS
Transport of particles includes Gaussian multiple Coulomb scattering with Gaussian range straggling for charged particles. Nuclear interactions are described by the intranuclear cascade/evaporation/fission model (Bertini or Isabel Inc. models) and nuclear elastic scattering is included for nucleon transport. The geometric description is that adapted from MCNP Version 3A. The transport of photons and low-energy neutrons produced in a LAHET calculation is accomplished by linking to MCNP Version 4B or 4C through a particle source file.

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM
The recommended upper limit for nucleon transport is 3.5 GeV; for pions, it is 2.5 GeV. Higher energies are possible, but the interaction physics is problematic. Muons are transported without nuclear interaction. Hydrogen and helium ions are generally restricted to interactions below 1 GeV/amu. Complete utilization REQUIRES the installation of MCNP Version 4B or 4C and the associated cross section libraries. MCNP is not included in LAHET but is available as CCC-700/MCNP4C and DLC-200/MCNPDATA..
