In an earlier investigation, the intense inner beta spectrum of Ru/sup 103/ was observed by Kondaiah to have an anomalous shape corresponding to a deficiency of electrons at low energy. This shape could not be explained by the generally accepted theory of beta decay. By use of a 4 pi betaray scintillation spectrometer, this beta group has been studied in coincidence with the 495-kev gamma ray. The Fermi plot of the data is now found to be linear down to 37 kev. The beta spectrum in coincidence with the 610-kev gamma ray was also measured. By a comparison of the total decay energies of the inner beta groups and their cascading gamma rays, it is deduced that the 610- and 495-kev gamma rays decay to the same energy level of Rh/sup 103/. The end-point energies of the two beta groups measured in coincidence with the 495- and 610-kev gamma rays are, respectively, 227 plus or minus 4 and 119 plus or minus 4 kev. (auth)
