The Positive Electron

Nature volume 132, pages 917–919 (1933)Cite this article

Abstract

THE discovery of the positive electron arose from the study of cosmic radiation by the cloud method1. Amongst the tracks of the particles of very great energy, associated with cosmic radiation, were found some which differed from the tracks of negative electrons only by being curved by a magnetic field in the opposite direction. Terrestrial sources of positive electrons of lower energy are now also available, since it has been found that they are produced when hard gamma rays are absorbed by matter, and also in certain cases of nuclear transformation. The production of positive electrons in the laboratory is therefore an easy matter.
