Ground-State Transitions in the Reaction ¹⁰B(n,t)⁸Be

Abstract

IN a recent communication, Frye and Gammel¹ have reported a study of the reaction ¹⁰B(n,t2α) for bombarding energies in the range 6–20 MeV. They give evidence which suggests that the reaction proceeds either via lithium-7 as an intermediate nucleus or as a three-body break-up. Their results indicate that if beryllium-8 takes part at all in the reaction, it occurs only in a very small fraction of the events; and they particularly remark on the absence of events leading to the formation of beryllium-8 in the ground-state.
