A review of existing data on nucleus‐nucleus collisions at Bevatron‐Bevalac energies (few GeV/nucleon) is given to test to what extent such collisions can be compared to nucleon‐nucleon studies performed at NAL and ISR energies. Data are examined for such phenomena as limiting fragmentation, scaling and factorization of cross‐sections. A brief discussion of experiments—either in progress or about to start, which bear on the question of testing high‐energy interactions models—is included.
