Abstract
A broad excited state was observed in 6He with energy Ex=5±1 MeV and width Γ=3±1 MeV, following the reaction 7Li(γ,p)6He. The state is consistent with a number of broad resonances predicted by recent cluster model calculations. The well-established reaction mechanism, combined with a simple and transparent analysis procedure confers considerable validity to this observation.
