Abstract

The available data on approximately forty $γ$ -emitting metastable states of isomeric nuclei has been compared with the present theories. Nearly all of the points lie near two straight lines when $log λ$ ( ${\sec .}^{- 1}$ ) is plotted against $log E$ (Mev). These lines fall close to the theoretical curves of Bethe calculated for electric $2^{4}$ and $2^{5}$ pole radiation.
