Abstract
The nuclide Kr with , produced in the reaction has been observed via β-delayed proton emission by using pulsed-beam technique. A single proton group at a laboratory energy of MeV with half-life of 32±10 ms was observed for the first time, corresponding to decay of the isobaric analog state in Br to the ground state of Se. Combining this result with a Coulomb displacement energy calculation yields a mass excess for Kr of MeV. The partial decay scheme of Kr is proposed.
