Abstract

The decay of the extremely neutron-deficient Ni48 was studied by means of an imaging time-projection chamber, which allowed the recording of tracks of charged particles. The decays of six atoms were observed. Four of them clearly correspond to two-proton radioactivity, providing the first direct evidence for this decay mode in Ni48. Two decays represent β-delayed proton emission. The half-life of Ni48 is determined to be T_1/2=2.1-0.4+1.4 ms.
