Transition from Thermal to Rapid Expansion in Multifragmentation of Gold Induced by Light Relativistic Projectiles
Abstract
Multiple emission of intermediate-mass fragments has been studied for the collisions of p, 4He and 12C on Au with the 4π setup FASA. In the case of 12C(22.4 GeV)+Au and 4He(14.6 GeV)+Au collisions, the deviations from a pure thermal break-up are seen in the energy spectra of the emitted fragments: the spectra are harder than calculated and than measured in p-induced collisions. This difference is attributed to a collective flow with the expansion velocity on the surface about 0.1 c (for 12C+Au collisions).
