Abstract:

A special vacuum chamber containing a lithium-drifted silicon detector and the radioactive source was designed for electron-gamma coincidences. The gamma rays were detected outside it with conventional scintillation counters. A further modification of this chamber was done placing into it a second silicon detector in front of the former, thus obtaining an electron-electron coincidence spectrometer. Conversion coefficients corresponding to the transitions of 0.161 MeV and 0.0795 MeV in Cs-133 were determined. An additional measurement of the conversion coefficient corresponding to the 0.279-MeV transition in Tl-203 was performed by means of beta continuum-electron conversion coincidences. Author
