The first measurements of the transverse momenta (pT) of heavy projectile fragments produced by fragmentation of 1.2-GeV/nucleon La are presented. The momentum distributions of the fragments (Z of about 26-56) are Gaussians and broader than predicted by models based on internal momenta of the projectile nucleons. The larger pT observed do not appear to be due solely to Coulomb effects, but are consistent with a simple model whereby nucleons from the (hot) overlap region recoil collectively into the (colder) projectile fragments. Thus pT and the fragment mass may provide a good indication of the vector impact parameter b.
