The beta spectra of Au/sup 198/, In/sup 114/ P/sup 32/, Y/sup 90/, and Cs/sup 137/ were determined with a scintillation counter (anthracene crystal) and an amplitude selector. The conversion electron peak of Cs/sup 137/ was used for the determination of the pulse-height energy calibration line. The maximum beta energy was determined by means of a Fermi-Curie analysis of the spectra, and the results were 0.928 plus or minus 0.05 Mev for Au/sup 198/, 2.10 plus or minus 0.02 Mev for In/sup 114/, 1/703 plus or minus 0.018 Mev for P/sup 32/, 2.42 plus or minus 0.02 Mev for Y/sup 90/, and 0.522 plus or minus 0.010 and 1.28 plus or minus 0.31 Mev for Cs/sup 137/. The maximum beta energy determination was made by means of the absorption curve to which the Feather analysis was applied (the absorption curve of P/sup 32/ serving as a standard). The results were 0.947 Mev for Au/sup 198/ and 2.02 Mev for In/sup 114/ . (tr-auth)
