Abstract
Multiplicities of intermediate-mass fragments (IMFs), neutrons, and ch arged particles were measured for Sn-112 + Sn-112 and Sn-124 + Sn-124 at E/A = 40 MeV. Significantly different scalings of the mean IMF mult iplicities with neutron and charged-particle multiplicities are observ ed for the two reactions. These differences can be qualitatively under stood in terms of fragment emission from an expanding evaporating sour ce for which the initial rates of cooling by neutron and light-charged -particle emission depend on the neutron and proton numbers of th sour ce according to statistical expectations.
