ADULTERATION OF THE PULSE-HEIGHT SPECTRUM IN THE SINGLE CHANNEL SPECTROMETER

The effect of the channel width, load-time constants, the integration time constants, and the scanning velocity on the shape of a photopeak was investigated on the Gaussian distribution curve y = e/sup -//sup x//sup 2/. For the variation of the maximum counting rate and the resolution, suitable approximation formulas were obtained for the practical range. The interaction of this adulteration with the statistical error was investigated in dependence on the channel width and the effect of the amplication. For the shortest possible scanning time, a rough formula was given. Measurements gave values which deviated by a maximum of 7% from the calculated values. (tr-auth)
