From gamma emissions to (n,xn) cross sections of interest: the role of GAINS and GRAPhEME in nuclear reaction modeling

During the last 10 years, in the general context of nuclear energy applications and future reactors development, our collaboration has performed measurements of (n,xnγ) cross sections to study (n,xn) reactions. Large sets of new and accurate experimental data have been produced on a variety of nuclei from 7Li to 238U. Comparisons with nuclear reaction code calculations have shown that the predictions of these exclusive cross sections are a real challenge for the theoretical codes. Indeed many processes are involved (evaporation, fission if fissionable nucleus, direct and pre equilibrium reactions, ...) which should be simultaneously well described by the models that using nuclear structure description for optical potential, level densities, decay scheme, etc. In this article, we review what we have learned since the last P(ND)2 workshop held in 2005 [1] and highlight how we can further progress in this field in order to provide new, complete, accurate and relevant experimental data.
