Transport model study of isospin diffusion around the Fermi energy domain

Swagata Mallik (VECC, Kolkata, India)

One of the most important applications of heavy-ion reaction around the Fermi energy domain is to study the nuclear equation of state at sub-saturation densities [1,2]. Boltzmann-Uehling-Uhlenbeck (BUU) equation based transport models are quite successful for explaining heavy-ion reactions at intermediate energies [3,4]. Transport calculation (BUU@VECC-McGIll) results of isospin diffusion will be presented. Effect of entrance channel and nuclear equation of state on isospin transport ratio will be discussed for ^58,64Ni+^58,64Ni reactions [5,6,7].
