A Search for Levels of 7Li Between 9·0 and 9·55 MeV Excitation

Abstract

The cross section of the reaction 6Li(n,3H)'He has been measured, with good energy resolution, over the neutron range 2·0--2·65 MeV. This corresponds to an excitation of 7Li from 9· 0 to 9· 55 MeV, a region in which photodisintegration experiments indicate the presence of one or more levels. No resonance structure was observed in this experiment and possible reasons for this are discussed.
