Abstract

le for neutron-induced cross sections of Mn-55 between 1 and 150 MeV. The evaluated le takes into account experimental data of the EXFOR data base and is generated by Bayesian statistics via the code GENEUS. Due to the scarcity of experimental data beyond 20 MeV, the prior, based on the nuclear model set of TALYS-1.0, plays an essential role for the reliability of the le in this energy regime. Therefore much eort was devoted to an optimized choice of the model parameters for the range 20 Z 28. Employing the recent formalisms a prior including parameter uncertainties and model defects was evaluated by GENEUS and used as a starting point of the evaluation process. In addition a careful analysis of experimental data was performed to estimate the covariance matrices of the experiments, which are used by GENEUS in the Bayesian procedure. The quality and the specic features of the evaluated data le and associated uncertainties are discussed.
