The MCEF code for nuclear evaporation and fission calculations

Abstract We present an object oriented algorithm, written in the Java programming language, which performs a Monte Carlo calculation of the evaporation-fission process taking place inside an excited nucleus. We show that this nuclear physics problem is very suited for the object oriented programming by constructing two simple objects: one that handles all nuclear properties and another that takes care of the nuclear reaction. The MCEF code was used to calculate important results for nuclear reactions,... Title of program: MCEF Catalogue Id: ADQC_v1_0 Nature of problem The competition between evaporation and fission is an important problem in intermediate and high energy nuclear reactions. Here, neutrons, protons, alphas and possibly other particles escape from the excited nucleus in competition with the fission process. Considering the fact that an exact calculation including all the channels in this nuclear reaction could be a complex problem, a statistical description of all these possible decaying modes could be a major simplification. In fact, rough analy ...
