Intranuclear Cascade Study of the Hadron-Nucleus Interactions at 1 GeV/c

摘要

The proton inclusive spectra measured with 800 MeV/c pi sup + beam (BNL) on light nuclei, and the 600 MeV/c /bar p/ beam (LEAR) on sup 6 Li and sup 63 Cu have been successfully interpreted in terms of the Intranuclear Cascade (INC) Model. According to the INC model predictions the /bar p/ induced reaction results in high pion yield for the light sup 6 Li target case. This is attributed to the nonavailability of nucleons to be knocked out by the pions produced following the /bar p/ annihilation. While in this case of the heavier sup 63 Cu target, some of the internally produced pions are subsequently absorbed, leading to thermal equilibrium of the nuclear medium, resulting in a softer proton spectrum at the high energy end. Based on the INC model predictions, the K sup + induced reactions could be studied to search for the ''true resonances'' beyond 1 GeV K sup + energy. 10 refs., 5 figs. (ERA citation 13:052536)
