Abstract

The decay of the isomeric pair^83gSe (T1/2=22.6 min, I^α = 9/2⁺) and^83mSe (T1/2=70 s, I^α = 1/2^-) has been reinvestigated using straight Ge(Li) (^83gSe and^83mSe) and Ge(Li)-Ge(Li) coincidence spectrometry (^83gSe). Both decays populate entirely different⁸³Br levels, 11 of them being previously unreported. From γ-ray unbalances and from the known isomeric cross-section ratio of⁸²Se, β^--branchings have been obtained, including a 34% branching of^83mSe to the ground state of⁸³Br. Log ft-values are deduced, spin and parity values proposed and discussed.
