Abstract: The two protons emitted in the decay of Zn54 have been individually observed for the first time in a time projection chamber. The total decay energy and the half-life measured in this work agree with the results obtained in a previous experiment. Angular and energy correlations between the two protons are determined and compared to theoretical distributions of a three-body model. Within the shell model framework, the relative decay probabilities show a strong contribution of the p2 configuration for the two-proton emission. After Fe45, the present result on Zn54 constitutes only the second case of a direct observation of the ground state two-proton decay of a long-lived isotope. © 2011 American Physical Society.
