Multifragmentation of the system [alpha]+[sup 197]Au has been studied at incident energies of 1 and 3.6 GeV/nucleon with the new 4[pi] setup, FASA. Mass, energy, and velocity of a few fragments are measured with high precision using time-of-flight telescopes, while for the other fragments, global multiplicity information is obtained from 55 CsI(Tl) detectors covering the main part of 4[pi]. Very high mean IMF (intermediate mass fragment) multiplicities of [l angle][ital M][r angle][sub IMF]=5.1[plus minus]0.8 are observed at the higher incident energy. Compared to the lower incident energy, they increase by 40%, indicating an increasing energy deposition with increasing incident energy. |
