Abstract
THE presence of heavy ionization tracks has often been observed in Wilson chamber photographs ; those due to the omission of a-particles from radioactive impurities can be easily eliminated. The rest are due to nuclear disintegrations produced by cosmic rays. Usually they emerge from lead plates placed inside such chambers. Photographs of disintegrations originating in the gaseous volume of a Wilson chamber are rare ; so far as is known to us, Anderson, and Neddermeyer1 have photographed one, and Zlotowsky2 another. The particles arc supposed to be produced by a nuclear evaporation process leading to the emission of both protons and neutrons ; in some cases a-particles have also been detected amongst them.
