Projectile multi-fragmentation study in the interaction of ⁸⁴Kr with nuclear emulsion detector at relativistic energy

A heavy-ion collision provides a unique opportunity to study the state of matter under extreme conditions of density and temperature. Nuclear fragmentation is an important experimental phenomenon in nucleus-nucleus collision at relativistic energy, since it carries the information about emission mechanism, phase transition of the nuclear matter as well as equation of state. The interesting feature of heavy-ion interactions is the variation of reaction properties with collision geometry. The compactness of the size, 4π detection capability, large range of ionization sensitivity and better resolution makes nuclear emulsion detector a unique detector in nuclear and particle physics experiment. Multi-fragmentation is one of the most important aspects of heavy ion collision. This work focus on the emission characteristics of the projectile fragments as well as their dependence on intermediate mass fragments produced in the interaction of ⁸⁴Kr (as projectile) with nuclear emulsion detector (as target detector) at kinetic energy of 1 GeV per nucleon.
