Abstract :
The relative angle correlation of intermediate mass fragments has been studied for p+Au collisions at 8.1 GeV. Strong suppression at the small angles is observed caused by IMF–IMF Coulomb repulsion. Experimental correlation function is compared to that obtained by the multibody Coulomb trajectory calculations with the various decay times τ of fragmenting system. The combined model, including the empirically modified intranuclear cascade followed by statistical multifragmentation, was used to generate starting conditions for these calculations. The model dependence of the results obtained has been carefully checked. The mean decay time of fragmenting system is found to be τ⩽70 fm/c.
