Evolution of Fragment Production as a Function of Excitation in 35C1 and 70Ge Projectile Breakup

Intermediate-mass fragment (IMF) production, typically 3≤;Z≤20, is a widely observed decay mode in heavy-ion reactions[1]. Possible scenarios to explain such a decay mode include bulk instabilities based on the expansion of hot nuclear matter with an initial compression stage in near-central collisions [2]–[4]. However, for such collisions, dynamical IMF production is also present as is evident from the observation of neck emission[5]–[7]. Also, the persistence of binary dissipative collisions[8]–[11] leaves a very small cross section for forming a hot and dense single source[12, 13]
