Abstract
The β+ decay of very neutron-deficient 43Cr was studied by means of an imaging time projection chamber that allowed recording tracks of charged particles. Events of β-delayed emission of one, two, and three protons were clearly identified. The absolute branching ratios for these channels were determined to be (81 ± 4)%, (7.1 ± 0.4)%, and (0.08 ± 0.03)%, respectively. 43Cr is thus established as the second case in which the β-3p decay occurs. Although the feeding to the proton-bound states in 43V is expected to be negligible, the large branching ratio of (12 ± 4)% for decays without proton emission is found.
