Inclusion of correlations in the empirical selection of intranuclear cascade nucleons from high-energy hadron-nucleus collisions
The very high energy (5 GeV to 20 TeV) hadron-nucleus differential particle production model found in the Monte Carlo transport code FLUKA87 has been adapted for inclusion in the transport code HETC88. The empirical selection of intranuclear cascade nucleons has been modified to provide simple correlations with the randomly selected number of hadron-nucleon collisions. A standard method of calculating the excitation energy of the compound nucleus preceding an added evaporation step by assuming the particles are produced in a one-dimensional nuclear well is applied. This method, coupled with the above correlations, leads to improved correlations of the excitation energy with the A and Z of the compound nucleus, and then to greatly improved distributions of the residual nuclei following evaporation. The frequency distributions of low energy (..beta.. < .7) charged particles show good agreement with experiment for 200 GeV protons incident on emulsions. Average multiplicities of shower and grey particles after evaporation for protons and pions incident on several elements are also compared with experiment. 23 refs., 10 figs., 1 tab.
