| 英文摘要 | 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 S-32 + Ca reaction. By reaction channel analysis and comparing with theoretical prediction, this new proton radioactivity was assigned to the beta-delayed proton decay of Kr-69 produced in the Ca-40 (S-32, 3n) reaction, corresponding to decay of the T = 3/2 isobaric analog state in Br-69 to the ground state of Se-68. Combining this measurement with the Coulomb displacement energy calculation yields a mass excess for Kr-69 of -32.15 +/- 0.30 MeV. The partial decay scheme of Kr-69 was proposed. |
