Abstract

The yield of particle-bound excited states of ejectiles produced in the reaction 9.5 MeV/nucleon 19F+159Tb has been determined by use of particle γ-ray coincidence techniques. The bound excited state population fraction for most projectile-like fragments shows no dependence on particle kinetic energy. In these cases the fractions are inconsistent with a Boltzmann population distribution, but they support the hypothesis of a substantial sequential decay component with a strong preference for the ground state of the residual fragment. For a few detected ejectiles there is a strong dependence of the excited state fraction on particle kinetic energy. This dependence is in agreement with that expected for a binary process in which the projectile-like fragment gets a small but constant fraction of the total available excitation energy.
