Possibility of the Existence of New Isotope 65Se
- Received Date: 1987-10-28
Abstract: A new beta-delayed proton precursor 65Se has probably been produced via the reaction 40Ca(28Si, 3n)65Se and identified from its beta-delayed proton emission. A single proton group at 3.75 + 0.05 MeV with half-life of was observed, corresponding to the 10.8±-3.7+4.1 superallowed beta transition of 65Se to the isospin analog state in 65As (the lowest T=3/2 state in 65As) then decaying by proton emission to the ground state of 64Ge. Because of poor statistics further experimental effort is required to confirm this discovery.
