Abstract:

A modified cascade model for hadron-nucleus collisions is proposed. The reaction probability (r(y)) is introduced with which the produced hadron in the first inelastic interaction is able to collide subsequently. The Monte Carlo computation is three-dimensionally carried out by using the appropriate inclusive spectra and energy dependence of multiplicities in hadron-nucleon collisions. The inclusive pseudo-rapidity spectra of shower particles are compared in detail for p-Em reaction at 200GeV/c and the data are in good agreement with the prediction when r(y) is linearly dependent on the rapidity, y. For the inclusive spectra and the multiplicities, the dependence on the incident energy and the atomic number of the target is compared with data. The results are satisfactory. The following points are made clear: The contribution of Fermi motion is small and almost negligible. The three-dimensional treatment shows the significant difference with that of one-dimension for the inclusive spectra, especially at low pseudo-rapidities.
