Sector Type Double Focusing Beta Ray Spectrometer Part II. Twin Setting Measurement of the Weak Higher Component of Cs¹³⁷

Abstract

A twin setting of two sector type double focusing beta ray spectrometers was used for measurement of the weak higher component of Cs¹³⁷ in order to remove completely the contributions resulting from the secondary causes. The measured spectrum agreed well with those of the previous results, which were therefore confirmed to provide a reliable basis for the analysis of the coupling constants in beta decay.
