Cascade-model for the Emission of Fast Li-fragment

Abstract

|
This paper is the last report on the Li-fragments emitted from the nuclear reactions caused by 28-GeV protons in Ilford G-5 nuclear emulsion. The first was on the slow Li-fragments (E＜60-MeV), which seemed to be emitted according to the evaporation theory. The second was on the Li-fragments (E≥60-MeV). Their energy and angular distributions were analysed and it was concluded that they were ejected by cascade model. This report, the last, is also on the fast Li- fragments. Here, the probability of ejection of a fast fragment (Z≥3) as a function of n_b or n_g or n_s which is the number of black, grey and schower tracks respectively, and the charge distribution of the fast fragments (Z≥3) were obtained. An analysis of this data once again gives the same conclusion that the fast Li-fragments are ejected by cascade model.
