Electrons are the main products of an extensive air shower and comprise approximately 90% of the shower. Since these electrons are the most numerous particles near the axis of a large shower and are not easily detected, extensive air showers are most easily studied by means of the electronic component. Thus, whatever concern there may be about the nucleonic cascade of which the electron is an outgrowth, it is necessary first to understand the development of the electronic component and is lateral and angular distribution. Also, for the correct analysis of any experimental data, it is of particular importance to know something about the angular distribution of the particles at the prescribed distance from the axis of the shower.
Since the actual tracks left by the electronic component can be photographed and analyzed, a cloud chamber was used [as] the principle place of equipment in this experiment. The results of this investigation furnished the basis of this paper. Details of the experiment, analysis of data, interpretation of results, and comparison of these results with those other experiments and theories are treated in subsequent parts of the paper.
