The World-Wide Variation of Cosmic Ray Intensity by the Electro-Magnetic Field

Abstract

The variation of cosmic ray intensity by the static electric field surrounding the earth was calculated in a previous paper. In it a greater advantage was indicated in explaining the cosmic ray intensity decrease at the time of the magnetic storm by the electric field hypothesis than by the magnetic field hypothesis suggested by S. Chapman. In the present paper, the intensity variations of the ionizing and neutron components produced by the variation of the static electric field are calculated in detail extending over various altitudes and latitudes. By comparing these calculations with observations, it can be concluded that this electric field hypothesis is possible in explaining the phenomenon of the world-wide variations in intensity pointed out recently by various authors.It may be possible that the diurnal variation of cosmic ray intensity can be produced by an electric field not derived from potential.
