Abstract

The dependence of intermediate-mass-fragment (IMF) element distributions on the multiplicity, [Formula Presented] of detected fragments has been measured for [Formula Presented] collisions at [Formula Presented], 55, 70, 100, 200, and 400 MeV. The observed dependence can be parametrized as [Formula Presented] where [Formula Presented] is a beam-energy and excitation-energy dependent parameter. Previous work indicated this parameter is zero in the liquid-gas coexistence region and positive in the gaseous phase. In contrast, we observe both negative and positive values for [Formula Presented], revealing the meaning of this parameter to be less straightforward than previously assumed. The magnitude of [Formula Presented] appears nonetheless to provide a nontrivial test of multifragmentation models.
