Alpha?Particles from the Reaction 7Li(p,g)8Be(a)4He

Abstract

The OI:-particle spectrum from the reaction 7Li(p,y)8Be*(0I:)4He has been determined in coincidence with y-rays_ The results indicate that, apart from the broad 2· 9 MeV level, there are no additional levels between the ground state and 7 MeV with intensities greater than 3 per cent. of the 2 . 9 MeV level. It is shown that the shape of the 2 -9 MeV level can be fitted satisfactorily by a dispersion formula if a large value for the reduced width of the level is assumed.
