BEHAVIOR OF 200A GEV S-32 AND FRAGMENTS IN COLLISIONS WITH A CU TARGET

Using CR-39 nuclear track detectors and an automated scanning system, the behaviour of 200 A GeV S-32 and projectile fragments with charges 9 less-than-or-equal-to Z less-than-or-equal-to 15 produced in collisi ons with a Cu target was studied. The total and partial fragmentation charge-changing cross sections of S-32, and the total cross sections o f fragments, were measured. We studied the dependence of the mean free path of secondary fragments on the distance from the emission point. We also measured the angular distributions of projectile fragments and the charge pick-up cross section of S-32 in Cu.
