A cloud-chamber study of the disintegration of oxygen and nitrogen

Abstract

A study of the disintegration of nitrogen and oxygen when bombarded by neutrons has been made by means of a cloud chamber. By observing the particles produced in the disintegration of the oxygen and nitrogen nuclei, data have been taken on several phenomena; the energy levels of carbon-13, boron-11, nitrogen-15, nitrogen-16, and carbon-14 have been studied; the range---energy relations of boron-11 and carbon-13 have been established over certain portions of their ranges; the relative probabilities of disintegration of the compound nuclei by different modes have been observed. In certain cases the angular distributions of the emitted particles have also been studied.
