Abstract

Some properties of fast, nonequilibrium splitting of projectiles in the Sn-124+Ni-64 reaction at 35A MeV were determined using the 4 pi CHIMERA detector system. In particular the charge distributions, in- and out-of-plane angular distributions, and relative velocities of projectilelike fragments were measured. The time scale of the process was estimated and it turned out that the process is sequential but much faster than the ordinary, equilibrated fission.
