An attempt has been made to determine the half-life for spontaneous fission for the "average uranium atom" with an argon-filled parallel-plate ionization chamber, employing the method of electron collection. A simple method of analyzing and extrapolating the observed fission counts from uranium deposits of various thicknesses has yielded the value （4.2±0.6）×1016years for this half-life. The mean range of fission fragments in uranium oxide is thereby found to be about 7.5 mg of uranium per cm2.

For a continuous function f（x） with a period 2π, M. Rietz proved that the αth order Cesàro means of the partial sums of its Fourier series uniformly approximated to f（x）. This paper gives the degree of approximation. We use {S（x）} to denote the partial sums of the Fourier series of f（x） and （C, α）, the αth order Cesàro means. Furthermore we define

An attempt has been made to determine the half-life for spontaneous fission for the "average uranium atom" with on argon-filled parallel-plate ionization chamber, employing the method of electron collection. The high vohage electrode contained an aluminum disk of 6.2 cm diameter on which was deposited a layer of uranium oxide prepared in the following manner. A known amount of uranium nitrate crystals was dissolved in alcohol and mixed with properly thinned colorless lacquer. The procedure then consisted in applying a small amount of the solution on the disk, baking it on an electric furnace to about 400癈 for five minutes, and repeating the process again and again until the desired amount of uranium had been deposited. The ionization pulses were observed on a Cenco cathode ray oscilloscope to which the output of the amplifier was connected.
