Abstract
WORKING in this laboratory, Szilard and Chalmers1 have shown that neutrons are liberated from beryllium irradiated by radium gamma-rays, and that they are capable of inducing radioactivity in a number of elements. Previously, Chad wick and Goldhaber2 had reported that, using an ionisation method, they had observed the liberation of protons from heavy hydrogen which was irradiated by gamma rays from thorium C.
