Abstract: We observe critical phenomena in spherically symmetric gravitational collapseof Einstein Cluster. We show analytically that the collapse evolution endseither in formation of a black hole or in dispersal depending on the values ofinitial parameters which characterize initial density and angular momentum ofthe collapsing cloud. Near the threshold of black hole formation, we obtainscaling relation for the mass of the black hole and find the critical exponentvalue to be 3-2. We numerically confirm that there exist wide ranges of initialparameter values around the critical configuration for which the model remainsshell-crossing free.
