Abstract

A 43-day isotope of cadmium has been discovered while irradiating cadmium with slow neutrons. The radiation consists of $β$ -rays of energy ∼1.5 Mev, and with approximately one 0.5-Mev $γ$ -ray per disintegration. By means of chemical separations, the radio element was identified as cadmium, and the mass assignment to ${}_{48}{Cd}^{115}$ was made by a fast neutron ${In}^{115} (n, p) {Cd}^{115}$ reaction.
