Abstract
The decay of81gSe and81mSe was investigated with Ge(Li) spectrometers and Ge(Li) gamma-gamma coincidences. Accurate energies, intensities and half-lives have been measured for 11 gamma-rays. These gamma-rays fit into a81Br level scheme with levels at: 275.9, 535.9, 538.2, 565.9, 649.7 and 828.2 keV. Beta component intensities were deduced from measured gamma intensities. The half-life is found to be (17.9±0.5) min for81gSe, and (57.28±0.05) min for81mSe.
