Partial cross section of projectile fragmentation in 197Au+27Al interactions at 1.015 GeV/n

The large fragmentation of 197Au projectiles at BEVALAC energy 1.015 GeV/n in Al target has been studied using a stack consisting of CR-39 (DOP) plastic track detectors. The partial cross-sections for the production of large fragments of charge ZF = 75 to ZF = 78 in collisions of 197Au beam of nuclei at 0.930 GeV/n in 27Al target has been estimated from the cone length distribution. The authors data found comparable to the expected results from the latest semi empirical model of Tsao et al. and that from the abrasion-ablation model of Townsend et al. The present data is in approximate agreement with the active and passive experimental data of Binns et al., and Gerbier et al. in Al target, respectively
