A stack consisting of CR39 plastics and Al target has been exposed to 1.015 GeV/n Au beamat an angle of 30 from LBL BEVALAC. About 5499 cone lengths of the Au beam and their fragments have been optically measured fromthe etched plastics kept below the Al target and the estimated partial cross-sections of large fragments for charges ZF ranging from 75 to 78 have been found comparable with the expected results from the semi-empirical model of Silberberg and Tsao. But those values are above the expected results from the abrasion-ablation model of Townsend et al. The observed charge pick-up cross-section for Z = +1 is found to lie below the global fit to the charge pick-up cross-section results surveyed by Westphal et al.
