Abstract
Multifragmentation in fully reconstructed events from 1A GeV Kr and La coll isions with C has been studied. Results are compared with similar data for 1A GeV Au+C. The emitted charged particles and fragments are identified wit h emission from either a prompt first stage or a second stage in which the remnant resulting from the first stage breaks up. The nuclear charge, mass, and excitation energy distributions of the remnant are determined. The tot al charged multiplicity, as well as those of the first and second stages ar e obtained. Freeze-out temperatures and thermal excitation energy permit th e determination of the caloric curve. The fragment charge distribution as w ell as the IMF multiplicity distribution and those of individual Fragments are obtained. The various results are examined as to the extent of universa l behavior when scaled for varying system size. Comparisons are made with i ntranuclear cascade and statistical multifragmentation model calculations.
