Two-proton radioactivity: The interesting case of ⁶⁷Kr and Further Studies

RADIOACTIVITY ⁶⁷Kr(2p), (β⁺), ⁵⁷Zn, ^59,61Ge, ^63,65Se, ^68,69Kr(EC), (β⁺), (β⁺p), ^55,56Cu, ⁶⁰Ga, ⁶³Ge, ^64,65As, ⁶⁷Kr(EC), (β⁺)[from ⁹Be(⁷⁸Kr, X), E=350 MeV/nucleon, followed by separation of fragments using BigRIPS and Zero Degree Spectrometer at RIBF-RIKEN]; measured E(p), I(p), Eγ, half-lives of decays of isotopes from time distribution of (fragment)(decay events) correlations using EURICA-WAS3ABi setup at RIKEN; deduced %2p for the decay of ⁶⁷Kr, and %β⁺p for ^59,61Ge, ⁶³Se, ^68,69Kr. Comparison with previous experimental results.
