Abstract

The primary fragments in 40Ca + 40Ca reactions at 35, 50, 80, 100, 140, and 300 MeV/u were simulated using the antisymmetrized molecular dynamics model, in the phase space at t = 300 fm/c with a coalescence radius R c  = 5 fm. The standard Gogny interactions g0, g0as, and g0ass were adopted in simulating the collisions at an impact parameter of b = 0 fm. It was found, using an isobaric yield ratio method, that temperature of the primary fragment depends on the incident energy and hardness of the interaction potential. The temperature obtained in this work agrees with the results by the self-consistent fitting method.
