THE POSSIBILITY OF EXITENCE OF NEW ISOTOPE 65Se

  •  Institute of Modern Physics,Academia Sinica,Lanzhou

  • A new beta-delayed proton precussor 65Se has was probably produced via the reaction 40Ca (28Si,3n)65Se and identified from its beta-delayed proton emission.A single proton group at 3.75±0.05MeV with half-life of 10.8±4.1/3.7ms was observed,corresponding to superallowed beta decay of 65Se to the isobaric analog state of 65As (the lowest T=3/2 state in 65As) then proton emitting to the ground state of 64Ge.Because of poor statistics further experimental effort is required to confirm this discovery.

Abstract: A new beta-delayed proton precussor 65Se has was probably produced via the reaction 40Ca (28Si,3n)65Se and identified from its beta-delayed proton emission.A single proton group at 3.75±0.05MeV with half-life of 10.8±4.1/3.7ms was observed,corresponding to superallowed beta decay of 65Se to the isobaric analog state of 65As (the lowest T=3/2 state in 65As) then proton emitting to the ground state of 64Ge.Because of poor statistics further experimental effort is required to confirm this discovery.
