Observation of Beta-Delayed Proton Decay of 69Kr

  •  Institute of Modem Physics, Chinese Academy of Sciences, Lanzhou, China

  • A new group of protons at laboratory energy of 4.07±0.05 MeV with half-life of 32±10 ms was discovered via observing the decay proton spectrum produced in the 32S + Ca reaction. By reaction channel analysis and comparing with theoretical prediction, this new proton radioactivity was assigned to the β-delayed proton decay of 69Kr produced in the 40Ca (32S, 3n) reaction, corresponding to decay of the T=3/2 isobaric analog state in to the ground state of 69Se. Combining this measurement with the Coulomb displacement energy calculation yields a mass excess for 69Kr of -32.15±0.30 MeV. The partial decay scheme of 69Kr was proposed.

Abstract: A new group of protons at laboratory energy of 4.07±0.05 MeV with half-life of 32±10 ms was discovered via observing the decay proton spectrum produced in the 32S + Ca reaction. By reaction channel analysis and comparing with theoretical prediction, this new proton radioactivity was assigned to the β-delayed proton decay of 69Kr produced in the 40Ca (32S, 3n) reaction, corresponding to decay of the T=3/2 isobaric analog state in to the ground state of 69Se. Combining this measurement with the Coulomb displacement energy calculation yields a mass excess for 69Kr of -32.15±0.30 MeV. The partial decay scheme of 69Kr was proposed.
