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.
