For this purpose, the isomer is obtained by the decay of its parent radionuclide Rb-83. In order to get more precise data on the gamma-rays occuring in the( 83)Rb/Kr-83m chain, we re measured the relevant gamma-ray spectra, because the previous measurement took place in 1976. The obtained intensities are in fair agreement with the previous measurement. We have, however, improved the uncertainties by a factor of 4.3, identified a new gamma transition and determined more precisely energies of weaker gamma transitions.
