Description

The β+ decay of 31Ar was investigated in an experiment at the GSI-FRS spectrometer. The ions of interest have been produced in the fragmentation of a 36Ar beam at 880 MeV/nucleon and implanted in a time projection chamber with optical readout. In addition to β-delayed one and two proton emission, for the first time the emission of β-delayed 3 protons has been observed. The branching ratio for this decay mode is found to be (0.07±0.02)%.
