Welcome to the NUCLEAR REACTION-DATA EVALUATION GROUP's Homepage!

The description of nuclear reactions represents an important test for both the appropriateness of reaction mechanism models and evaluation of nuclear data requested for applications. Basic problems are still present in neutron data evaluations even in the advanced nuclear reaction models presently involved within, e.g., the Joint Evaluated Fission and Fusion File (JEFF) evaluated nuclear data project. The nuclear data topic is considered a critical task for selecting and validating the best materials for constructing fusion power reactors, so that it is a priority of the EC domestic agency Fusion for Energy (F4E) related to the International Thermonuclear Experimental Reactor (ITER) and International Fusion Material Irradiation Facility (IFMIF) fusion programmes. Overall, the theoretical description of the neutron interactions with nuclei needs significant improvements that could be validated by suitable description of experimental data within also the F4E Framework Partnership Agreement No. F4E-FPA-168 (2011-2014). At the same time, following our local results as well as in order to additionally check them, connection of computational studies and further measurements is planned. It is thus concerned participation to proposal and performance of further experiments at n_TOF/CERN and NFS/SPIRAL-2 facilities.

A particular case is that of the deuteron-induced reactions since, due to the weak binding energy of the deuteron, B=2.224 MeV, there is a variety of reactions initiated by the neutrons and protons coming from deuteron breakup. Simultaneous analysis of deuteron elastic scattering and induced activation appears essential for a consistent input of nuclear model assessment, for further estimation of deuteron interaction data. Third, usually neglected or very poorly taken into account, the stripping (d,p) and (d,n) and the pick-up (d,t) reactions description is still an open question. Our grup aims to deeper understanding of all above-mentioned problems of deuteron interactions, also through the IAEA Research Agreement No. 14996 (2008-2012) within Fusion Evaluated Nuclear Data Library (FENDL-3) project of IAEA Nuclear Data Section.

A simultaneous analysis of the α-particle elastic scattering and induced activation has been also essential for a consistent input of nuclear model assessment for the α-particle OMP that led to a recommended segment of the Reference Input Parameter Library (RIPL-3) project.
