  Nuclear multifragmentation is an important phenomenon, the study of which can
throw light on reaction mechanism in heavy ion collisions at intermediate and
high energies. Based on statistical and dynamical model studies, this thesis is
concentrated mainly on, the following three aspects of nuclear
multifragmentation reactions namely (i) production of exotic nuclei which are
normally not available in the laboratory (ii) nuclear symmetry energy from
heavy ion collisions at intermediate energies and (iii) Nuclear liquid-gas
phase transition. In addition to these equivalence of statistical ensembles
under different conditions is also studied in the framework of
multifragmentation.
