New charge exchange model of GEANT4 for ${}^9$Be(p,n)${}^9$B reaction

Abstract

A new data-based charge exchange model of GEANT4 dedicated to the ${}^9$Be(p,n)${}^9$B reaction is developed by taking the ENDF/B-VII.1 differential cross-section data as input. Our model yields results that are in good agreement with the experimental neutron yield spectrum data obtained for proton beams of energy $(20\sim 35)$ MeV. In particular, in contrast to all the considered GEANT4 hadronic models, the peak structure resulting from the discrete neutrons generated by the charge-exchange reaction is observed to be accurately reproduced in our model.
