A Hauser-Feshbach compatible unified exciton model
Description
The conditions under which the unified exciton model leads in its equilibrium limit to the Hauser-Feshbach model are derived and discussed. A simple extension of the exciton model is presented which exhibits the desired equilibrium behaviour. To this end, angular momentum dependent escape and spreading widths are derived. Both pre-equilibrium and equilibrium decay to specific isolated levels are discussed. (orig.)
