Onset of multifragmentation and vaporization in Au-Au collisions

Various phenomena such as incomplete (and complete) fusion-fission at low incident energies as well as multifragmentation or a complete disassembly of the nuclear matter are the typical characteristics seen in a heavy-ion reaction. Lot of experimental and theoretical studies are reported in the literature during last two decades on the breaking of colliding nuclei into pieces of different sizes. Therefore, in the present study, we present a systematic study of the multifragmentation for the reaction of 197Au+197Au over entire incident energy and impact parameter range. The quantum molecular dynamics (QMD) model is used for the present study
