Abstract

Collective transverse flow of nuclear matter was measured as a function of the ratio of neutrons to protons ( $N / Z$ ) of the interacting system for the first time. The collisions of three isotopically pure beams of $A = 58 nuclei$ with two $A = 58 targets$ were studied at 55 MeV/nucleon. The results for the flow variables demonstrate the sensitivity of transport models to elementary aspects of the nucleon-nucleon collisions.
