Abstract

Angular distributions of projectile-associated He fragments from Au induced reactions in nuclear emulsions at 10.7 A GeV have been measured with a precision of ±0.1 mrad. Two emission components are indubitably appearing, one representing fragmentation of a fermionic system while the other one exhibits large transverse momentum transfer. Possible explanations for the latter component are discussed.
