Measured activation cross sections below 10 MeV for the 51V(n, p) 51Ti and 51V(n, α) 48Sc reactions

Abstract

The activation method is used to measure cross sections for the 51V(n, p) 51Ti reaction from E n = 2.856 to 9.267 MeV and for the 51V(n, α) 48Sc reaction from 5.515 to 9.567 MeV. Both measurements utilize ENDF/B-V evaluated neutron-induced fission cross sections of 238U as a standard. The experimental results from this work are compared with corresponding ENDF/B-V evaluated cross sections for V and substantial differences are evident. The most significant difference is a tendency for the measured values to exceed evaluated ones by as much as 50% in the vicinity of 8 MeV.
