Efforts in Bologna on quasiparticle level density systematics and on comparison and development of different approaches to preequilibrium reaction mechanism

We present a summary of activities carried out at ENEA in Bologna on the development of the preequilibrium emission models. We start with the first application of the Multistep Compound Model in the Heidelberg formulation, which is followed by the Multistep Direct calculations. Next, the comparison between the exciton and Multistep Compound model by Feshbach, Kerman, and Koonin is presented. Finally we discuss energy and isotope dependence of the average single particle level spacing. (author). Refs, 9 figs
