Abstract : A knowledge of the penumbra of the cosmic radiation is becoming increasingly important for a number of cosmic-ray measurements, particularly for those measurements employing geomagnetic effects as part of the sensor discrimination techniques. Although the penumbra has an extremely complex structure of allowed and forbidden bands, the authors have found that up to approximately 10 GV the penumbral width can be approximated by a simple power law relationship.
