Abstract

Short-lived neutron-rich nuclei including 93Br, 93Kr, and 94Kr were produced in proton-induced fission of 238U at the Holifield Radioactive Ion Beam Facility in Oak Ridge. Their β decay was studied by means of a high-resolution online mass separator and β-γ spectroscopy methods. The half-life of T_1/2 = 152(8) ms and β-delayed branching ratio of P_n = 53-8+11% measured for 93Br differs from the previously reported values of T_1/2 = 102(10) ms and P_n = 68(7)%. At the same time the half-life of 94Kr T_1/2 = 227(14) ms and both the half-life of T_1/2 = 1.298(54) s and β-delayed branching ratio of P_n = 1.9-0.2+0.6% of 93Kr are in very good agreement with literature values. The decay properties of 93Br include previously unreported γ transitions following β-delayed neutron emission.
