Abstract
LEA'S observations and Fermi's pioneer work has shown that many elements may capture a neutron, and emit gamma rays in the process. This phenomenon has been further investigated especially by Rasetti1, and more recently by Kikuchi2 and Fleischmann3, who used polonium-beryllium, deuteron-deuterium and radon-beryllium sources respectively.
