Abstract
Angular distributions of projectile-associated He fragments from Pb in duced reactions on stationary Pb target at 158 A GeV/c incident moment um are reported, The precision of the angular measurements was about /-0.01 mrad, Two emission components are appearing in the projected an gular spectra of the He particles, one representing fragmentation at F ermi momentum scale, while the other one exhibits large transverse mom entum transfer. By scaling with the incident momentum the angular spec tra of He particles are compared with earlier reported measurements of Au on Au interactions at 11.6 A GeV/c, The p(T) spectrum of the He pa rticles appears the same for the two cases.
