Dynamic evolution and the caloric curve for medium mass nuclei

Abstract Self-consistent coalescence model analyses of light particle emission have been used to follow the evolution of the temperatures and densities of A ≈110 nuclei produced in violent collisions induced by four different 47 A MeV projectiles. The degree of expansion of the emitting system increases with increasing projectile mass. The caloric curve derived for these expanding A ≈110 nuclei plateaus near T =7 MeV. The plateau extends from 3.5 to 6.9 MeV/u excitation energy.
