Gamma-Ray Energies in the Decay ofCs134

Abstract

The photoelectric conversion spectrum of gamma rays in the decay of ${\mathrm{Cs}}^{134}$ was studied with a newly installed Siegbahn-Slätis beta-ray spectrometer, using a strong source and thick lead and uranium radiators to bring out weak lines. Lines corresponding to the following gamma rays were found (expressed in kev) 467; 553; 571; 607; 794; 1027; 1164; 1368; 1401.
