Analysis of the intermediate stage in the heavy ion interactions of {sup 208}Pb+{sup 197}Au and {sup 197}Au+{sup 197}Au

Abstract

Two different projectiles {sup 208}Pb and {sup 197}Au at the same energy (11.67MeV/u) have been bombarded on {sup 197}Au target to study heavy ion interactions using mica as a passive detector. In this paper we present results on the study of energy damping and time scale of the existence of di-nuclear composite system in the intermediate reaction step. The plots of Q-values as well as reaction cross sections in various angular bins of scattering angles suggest that K.E. damping was complete and dynamic equilibrium was established between the first and second reaction steps. The time scale of this duration was also determined.
