Excited States of 8Be From the 7Li(d,n)8Be Reaction

Abstract

The energy spectrum of neutrons from the reaction 7Li(d,n)8 Be at 700 keV bombarding energy has been studied with nuclear emulsions at 0, 75, and 135°. Both resolution and statistics compare favourably with those of previous nuclear emulsion measurements of this spectrum. The results do not confirm the suggestions made by earlier workers that levels at 2·2, 4·1, 5·3, and 7·5 MeV in 8Be participate in the reaction, and support the view that the only excited state below 9 MeV in 8Be is the well-known broad level at 2·9 MeV.
