Analysis of the intermediate stage in the heavy ion interactions of Pb-208+Au-197 and Au-197+Au-197

摘要

Two different projectiles Pb-208 and Au-197 at the same energy (11.67 MeV/u) have been bombarded on Au-197 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. (C) 2008 Elsevier Ltd. All rights reserved.
