Limiting fragmentation of target nucleus at high energy

摘要

This study discusses features suggestive of a nuclear multifragmentation in the target. A wide range of projectile masses are used (A_(Proj) = 1-207) over a large energy region (E_(lab) = 1A-200A GeV). In particular, the validity of the nuclear limiting fragmentation hypothesis is focused in the target region. The probability that the target is fragmented forms about 90% from the total inelastic geometrical cross section. The dependence of the target fragmentation cross section on the system size and on the incident energy is presented. The results are analyzed in the framework of the modified FRITIOF simulation code.
