  The relative angle correlation of intermediate mass fragments has been
studied for p+Au collisions at 3.6 GeV. Strong suppression at small angles is
observed caused by IMF-IMF Coulomb repulsion. Experimental correlation function
is compared to that obtained by the multi-body Coulomb trajectory calculations
with the various decay time 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 85 +- 50
fm/c.
