Latitude Effect of Penetrating Cosmic Ray Showers

Abstract

IT has been shown by Broadbent and Jánossy1 that penetrating cosmic ray showers are of two types : (a) local penetrating showers ; (b) extensive penetrating showers. Local penetrating showers are supposed to be produced by primary nucleons, and they give rise to a transition effect which is proportional to mass. Extensive penetrating showers appear to be parts of extensive air showers. They show a strong transition effect in lead but almost none in paraffin.
