At intermediate energies, nuclear reactions have a crucial significance in nuclear physics and in science in general, which is reflected by the wide industrial scope of applications of these reactions. In this book, the fundamental theoretical ideas of the (Exciton Model), one of the most promising statistical models used to interpret such reactions, are listed, and some convenient calculations are made. Practical focus is given to the important quantity needed in this model, the (Level Density, LD). Taking the basic definition as a start, the LD is then calculated for a wide range of...

This is the second part of "The Exciton Model", a book aimed to explain the theoretical approach needed in Preequilibrium Emission (PE) spectra calculations. In Part I of the book, the nuclear level density calculations based on the Equidistant Spacing Model (ESM) were given. The focus was then driven to the simple, yet useful, approach of the ESM, while in this part, the idea of the non-ESM, i.e., the real energy distribution scheme of the nuclear levels will be considered. This represents the non-approximated model of level density. Beside the above, the important steps needed during PE...
