The ??Decay of 8B, and 2+ States Of 8Be

Abstract

The {l-decay of 8B has been investigated by measuring the energy distribution of the <x-particles from subsequent breakup of 8Be. The data have been analysed, in conjunction with data from <X-o< elastic scattering, in a three-level R-matrix formalism. Consistent fits are obtained for a channel radius of 6·0±0·5 fm, and the existence of a broad 2+ state of 8Be near 12·0 MeV, of width 14 MeV, is confirmed.
