摘要：

Collisions between Ar-36 projectiles and Au-197 target nuclei at E/A = 50, 80 and 110 MeV have been studied with the MSU Miniball, a 4pi phoswich array with a low detection threshold. Various impact-parameter filters, based upon total charged-particle multiplicity, transverse energy, mid-rapidity charge and multiplicity of emitted hydrogen nuclei, are compared and cross-correlated. The relative selectivity of each prescription for small impact-parameter collisions is evaluated by assessing the suppression of fast-particle emission at forward angles.
