Abstract
R. S. Krishnan and D. H. J. Gant have bombarded silver with deuterons from a cyclotron. They find a negative electron activity of period 2·4 min. Chemical separation of the irradiated silver into silver and cadmium fractions lias been carried out. The cadmium fraction contains a body of 6·8-hr. period emitting soft negative electrons, possibly due to a cadmium isotope; the silver fraction contains a body of 26-min. period emitting positrons. N. Feather has confirmed some of the previous workers’ findings, using the method of critical absorption.
