Abstract

The β+ decay of very neutron-deficient Cr43 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. Cr43 is thus established as the second case in which the β-3p decay occurs. Although the feeding to the proton-bound states in V43 is expected to be negligible, the large branching ratio of (12±4)% for decays without proton emission is found.
