Emission of 24Na fragments in the interaction of 197Au with intermediate-energy pions and protons

Description

Excitation functions for the formation of 24Na from 197Au have been measured for incident π+ between 176 and 368 MeV, π- between 239 and 368 MeV, and protons between 197 and 800 MeV. The cross sections increase sharply with energy and at any given energy obey the relation sigma/sub pi+/ > sigma/sub pi-/ > sigma/sub p/. The results are analyzed in terms of the contribution of hot-spot and coherent-cascade mechanisms to the proton yields. The role of statistical phase-space factors, as embodied in cascade-evaporation calculations, is invoked to explain the ratio of π+ and π- cross sections
