Evaluation of the Fast Neutron Cross Sections of 46, 47, 48, 49, 50Ti Including Complete Covariance Information

A new evaluation of all-important neutron cross sections of the stable isotopes of Ti was performed in the neutron energy range 0.2-20 MeV, which is the whole energy range above the resonance region. The evaluation combines the results of recent nuclear model calculations (prior) and the complete existing experimental database by means of the Bayesian code GLUCS03 in order to obtain the most accurate description of the cross sections (posterior) within our present knowledge. The evaluation of the total cross section is completely based on the accurate experimental database for natural Ti. The results of the evaluation, files 3 (cross sections) and files 33 (cross-section covariances) for all stable isotopes of Ti will be part of the new isotopic evaluations for Ti for the Joint European Fission and Fusion (JEFF) file
