Abstract
The reaction of Cl35 with Ta at 20 MeV/nucleon has been observed to produce pairs of complex projectile-like fragments. These fragments are emitted far from the target following the stripping of nucleons from the projectile to form an excited primary ejectile. The inelasticity of the reaction with the target is midway between a fully damped and a quasi-elastic collision. The spectra of relative fragment energies agree with an equilibrated distribution of excitation energy in the primary ejectile, thus supporting the hypothesis that the fragments are the products of a statistical decay process.
