Abstract

USING the cloud chamber method, we1 have investigated the beta-ray spectra of 24Na. The K.-U. plot showed clearly the existence of two groups. The energy difference between the higher energy group and the lower one is about 1 Mv., their relative intensities being 2, 3 and 1 respectively. The higher energy group lies on the first forbidden Sargent curve, for which Δi = 1, while the lower one is on the permitted Sargent curve, Δi = 0.
