The nucleon-nucleus and nucleus-nucleus total reaction cross sections are of importance in many different fields, both for a better theoretical understanding as well as for a number of applications. The total reaction cross section determines the mean free path when particles traverse nuclear matter, and the production cross sections for secondary particles are directly proportional to it....

The Full Bayesian Evaluation Technique has been developed for nuclear data evaluation and provides a consistent set of nuclear reaction cross sections and associated uncertainty information in form of covariance matrices. The technique is based on the concept of Bayesian statistics, which is the proper mathematical tool accounting simultaneously for the a-priori knowledge as well as for the...

In spring 2010 a Full Bayesian Evaluation of neutron-induced reactions on Mn-55 in the energy range between 5 and 150 MeV was presented. This evaluation was based on a prior, which included the effect of parameter uncertainties and for the first time also model defects. It turned out that the latter have a remarkable impact on the final evaluation although only a first coarse approach has been...

The pre-equilibrium emission model inconsistencies found within attempts to describe unitary the nucleon-induced reaction cross sections up to 60 MeV, are still actual. Both global and local approaches have been used for a consistent analysis of the available activation data for all stable isotopes of medium-mass elements, available up to 50 MeV, and conclusions on particular model assumptions...

The Joint Research Activity 1 of EFNUDAT was dealing with the development of novel data acquisition techniques for nuclear data measurements based on wave-form digitization. JRC-IRMM was involved in the development of fast digital data acquisition systems as well as digital signal processing (DSP) routines for off-line treatment of the sampled signal wave-forms.
Two different digital data...
