Correlated two-proton decay from C10

The decay of C10 excited states to the 2p+2α exit channel has been studied using inelastic excitation of a secondary C10 beam. The decay sequences leading to the 2p+2α final state are determined for the previously known levels and for a newly found level at E*=8.4 MeV. A state at E*=6.57 MeV is shown to undergo two-proton decay to 8Beg.s. with strong p-p correlations consistent with the S1 phase shift. Based on the lack of such correlations for other two-proton decays, this indicates that the correlations are associated with structure of the parent level.
