Abstract
SEVERAL investigators have reported finding positive particles emitted from β-emitters1–8, in numbers very much greater than allowed by the theory of pair production either by γ-rays or β-particles. In some cases positive particles have been found to the extent of 1 per cent of the β-radiations from substances which are not γ-emitters4,7, and in others positive particles of surprisingly high energy have been detected7.
