摘要：

Proton cross sections with associated multiplicities have been measured in 139LA + 139La collisions at E/A = 138 and 246 MeV. Data were taken at center of mass angles between 40° and 90°. At both energies the inclusive proton cross section is approximately isotropic over the range of CM angles covered. At E/A = 246 MeV the angular distribution of protons depends strongly on the associated multiplicity. We discuss the possibility that hydrodynamic flow of nuclear matter is manifested in the semi-inclusive cross section. © 1990.
