The results obtained indicate the principal applicability of these Rb-83 sources for monitoring the stability of the energy scale of electron spectrometers in the 20 keV region at the level of +/-60 meV for at least two months, which corresponds to the requirement of the new KATRIN tritium neutrino project. Investigations are being continued using sources produced by implantation of Rb-83 ions into different substrates.
