Multifragmentation in Heavy Ion Nuclear Reactions

Abstract

The present work deals with the theoretical study of multifragmentation and it's associated phenomena in heavy-ion collisions. Firstly, we give some details about the experiments, their theoretical concepts and experimental set ups held in past years in which multifragmentation data obtained at the SIS/GSI accelerator is reviewed using heavy ion beams with (0.1-1)A GeV together with the ALADIN and FOPI experimental setups. After that, we discuss various models used to study multifragmentation in recent years. This work is done within the framework of Quantum Molecular Dynamics (QMD) model. This model allows to study the influence of several types of nucleonic interactions on a large variety of observables and phenomena occurring in heavy ion collisions at relativistic energies. Finally, we give qualitative analysis of various results obtained theoretically in multifragmentation and also compare some of our results with those obtained experimentally from ALADIN experiment.
