Abstract

Particle track photography with thick photographic emulsions has obtained great importance for the development of nuclear physics and elementary particle physics. One of the advantages of this technique for the study of nuclear reactions and elementary particles stems from the possibility of observing individual interactions after introduction of target nuclei into the emulsion. When this is done, the photographic plate plays the role of both detector and target and contains the nuclei of the elements contributing to the emulsion components, as well as the nuclei of elements introduced (loaded) into the emulsion in some way, depending upon the particular problem under consideration. Depending upon the purpose of the study, in order to increase the efficiency of an experiment one must try to increase the concentration of the nuclei of elements which are anyhow contained in the emulsion (in order to increase the scanning efficiency), or one must introduce as many as possible heavy (or light) nuclei originally not contained in the emulsion. This is a difficult problem because one must maintain the principal properties of the photographic emulsion which is composed of certain elements in a specific way. Particular difficulties are encountered when the emulsion is provided for recording particles at the ionization minimum.
