Vertical Cutoff Rigidity and the Intensity Distribution of Cosmic Rays near Cape Town.
A fairly sharp increase of 2.3% in the intensity of the nucleonic component of cosmic rays was observed at 30,000 feet pressure altitude along a contour of CONSTANT CALCULATED VERTICAL CUTOFF RIGIDITY ON A RESEARCH FLIGHT FROM Cape Town, South Africa, at 18 E longitude, to a point 2 W longitude.
