β-delayed three-proton decay of ³¹Ar

RADIOACTIVITY ³¹Ar(β⁺p), (β⁺2p), (β⁺3p)[from ⁹Be(³⁶Ar, X), E=880 MeV using FRS separator at GSI]; measured Ep, Ip, (³¹Ar)p-coin using gaseous optical-readout time-projection chamber (OTPC), TOF and energy loss information; deduced branching ratios for β⁺p, β⁺2p and β⁺3p decay modes, Gamow-Teller strength distribution. Comparison with previous experimental results.
