RAPIDITY DISTRIBUTIONS OF CA + CA, NB + NB, NE + AU AND AU + AU AT BOMBARDING ENERGIES FROM 250 TO 2100 MEV NUCLEON

We present experimental rapidity distributions d Nch/d y over a wide range of bombarding energies and projectile and target masses. Target and projectile spectators are observed for peripheral collisions but not for the most central collisions. This behavior is found for all systems and bombarding energies investigated. Although detector inefficiencies tend to distort the experimental distributions, they are on a tolerable level and do not remove sensitivity to theoretical descriptions. © 1990 Springer-Verlag.
