Comparison of methods for calculating cross sections at high energies in astrophysics.
Abstract
An investigation is conducted concerning the relative merits of current techniques for calculating highenergy nuclear reaction cross sections. It is found that a use of semiempirical equations has advantages if interactions with a large set of different target nuclides have to be considered. The computation time in such a case is about 3 orders of magnitude less than for Monte Carlo calculations. Only semiempirical techniques are currently applicable to fission and fragmentation reactions. Monte Carlo calculations must be used for neutroninduced reactions, because semiempirical calculations for such reactions have not been developed.
