Radioactive sources of the monoenergetic low energy conversion electrons from the decay of isomeric 83mKr are frequently used in the systematic measurements, particularly in the neutrino mass and dark matter experiments. 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.
