Abstract

Cross sections of iridium and platinum isotopes have been measured, which were produced as fragments from 197Au projectiles interacting with aluminum target nuclei at 1 A GeV. The fragments were identified by a kinematic analysis (ΔE-time-of-flight) and by an ion-optical separation at the projectile-fragment separator FRS at GSI. Indications are found for high excitation energies and weak proton-neutron correlations in the peripheral nuclear-collision process.

      COFRA is a simplified version of the abrasion–ablation reaction model by Gaimard and Schmidt [28]. COFRA includes a full description of the abrasion process where the number of nucleons removed from projectile/target is described according to the geometrical approach [29] and the excitation energy gained in this process is obtained from the energy distribution of the holes produced by the abraded nucleons [30]. The second stage of the reaction is then described under the assumption that residual nuclei with a large neutron excess de-excite exclusively by neutron evaporation.
