R-Matrix Evaluation of¹⁶O Neutron Cross Sections up to 6.3 MeV

Abstract

AbstractWe have evaluated 16O neutron cross sections in the resolved resonance region with the multilevel Reich-Moore code SAMMY. Resonance parameters were determined by a consistent analysis, including both Doppler and resolution broadening effects. To properly treat the α particle exit channel, an algorithm to calculate charged particle penetrabilities and shifts was incorporated into SAMMY.Keywords: resonance parameter evaluationoxygen 16neutron cross sectionsalpha particle exit channel
