Abstract

The beta-ray spectra of Ra E and

P^{32}

were obtained by means of a magnetic spectrometer of high resolution. The observed end points of the spectra of Ra E and

P^{32}

are at 5280±20

H_{ρ}

(1.15 Mev) and 7150±100

H_{ρ}

(1.69 Mev), respectively. The end points obtained by extrapolating the Konopinski-Uhlenbeck plots are in each case about 17 percent greater than the observed ones, indicating that for some spectra these plots should not be used to determine the upper limits.
