Decay particles from the s-hole states in 11B, 15N and 6He have been measured in coincidence with the quasifree 12C(p, 2p), 16O(p, 2p) and 7Li(p, 2p) reactions at 392 MeV incident energy. Triton-decay is found to be larger than α-decay for both s-hole states in 11B and 15N despite its smaller Q-value than that, of α-decay. This supports the selection rule predicted by the microscopic SU(3 -model calculations. The relation between the 6He(s-hole) state and the di-triton cluster structure recently found from the charge exchange reaction is briefly discussed.
