Cloud Chamber Photographs of the Cosmic Radiation focuses on cloud chamber and photographic emulsion wherein the tracks of individual subatomic particles of high energy are studied.
The publication first offers information on the technical features of operation and electrons and cascade showers. Discussions focus on the relationship in time and space of counter-controlled tracks; techniques of internal control of the cloud chamber; cascade processes with artificially-produced electrons and photons; and nuclear interaction associated with an extensive shower.
The manuscript then elaborates on nuclear disintegrations and interactions of secondary particles and V-particles. Topics include neutral V-decays in which one secondary can be identified; nuclear disintegrations in a thick lead plate; penetrating shower in a high pressure cloud chamber; and products of an energetic star in the gas of the cloud chamber.
The publication is a reliable reference for readers interested in the study of cloud chamber photographs and cosmic radiation.
