Neutron Data Evaluation and Validation of Rhodium-103.

Rhodium-103 is a prominent fission product in nuclear reactors as well as a usual detector in fast neutron activation or dosimetry techniques. The neutron-induced reactions and the energy regions of interest differ significantly depending on the applications. In this paper, a new evaluation spanning the 0- to 30-MeV energy range is described. The quality of the transitions between the various energy intervals was assessed with the help of statistical techniques to test the resonance parameter distributions and the SPRT method to check optical model calculations. The evaluated nuclear data file was verified and processed. The quality of the data was successfully tested against both differential and integral results for activation, thermal and fast reactor applications. This new file should be part of the upcoming JEFF-3.1 library. © 2005 American Institute of Physics [ABSTRACT FROM AUTHOR]
