Abstract

The quantum mechanical calculations of Knipp and Uhlenbeck, and F. Bloch of the continuous $γ$ -spectrum associated with the sudden change of nuclear charge during $β$ -decay have been extended to forbidden $β$ -transitions and to the different types of $β$ -interactions. It is shown that the $γ$ -spectrum has practically the same shape, and the ratio of total $γ$ -intensity to $β$ -intensity is almost the same for forbidden transitions as for allowed transitions, irrespective of the $β$ -interaction. This accounts for the good agreement of the theory for allowed transitions with the experiments of C. S. Wu on ${}_{15}P^{32}$ , a "forbidden" $β$ -emitter. A simple classical analogue is given to explain this uniformity and is shown to justify the interpretation that the probabilities for the $β$ - and $γ$ -emission processes may in a very good approximation be taken as independent.
