Multifragmentation in (84)Kr + (197)Au collisions at beam energies of E/A = 35, 55, 70, 100, 200, and 400 MeV.

摘要

This dissertation concerns investigations of multifragmentation processes induced by ;These experimental data were compared to several dynamical and statistical multifragmentation models. The Quantum Molecular Dynamics model (QMD) was generally unable to describe the experimental trends, a failure that may be related to the classical heat capacities of the computational nuclei. The Statistical Multifragmentation classical heat capacities of the computational nuclei. The Statistical Multifragmentation Model (SMM), on the other hand, could successfully describe the average fragment multiplicities, and charge distributions, but failed to describe the dependence of the fragment charge distribution on the fragment multiplicity. This latter failure indicates an internal inconsistency within the SMM approach whose origin will require additional theoretical study.
