Experimental investigations of the reaction processes of the system Au+V at a laboratory energy of 447 MeV
Abstract
Damped and fusion/fission-like reaction processes of the heavy-ion system 197 Au + 51 V were studied in order to obtain a complete picture of the reaction mechanisms associated with a strong dissipation of the kinetic energy and a small relaxation of the mass asymmetry. Angular, energy, and mass distributions of the projectile-like and the fission fragments were measured. Using a phenomenological analysis of the relation between the reaction angle of the damped phenomena (elastic scattering) and the kinetic energy, the deviation function for the system AU + V was deduced, showing negative values for small angular momentum. Angular-momentum dependent reaction times were determined from this experimental deviation function. The comparison of the fragment charge distributions with data from other reactions shows a qualitative agreement for the damped reaction processes. The experimental data and a dynamic reaction model show a good agreement with the predictions of a transport model based on the exchange of nucleons.
