SOME CONSIDERATIONS ON THE ANALYSIS OP PRIMARY COSMIC RAY INTENSITY EXPERIMENTS

摘要

A discussion is given of the procedures employed in the analysis of primary cosmic ray intensity experiments and the assumptions inherent in their use, with particular emphasis on nuclear emulsion as a detector. Explicit formulae for extrapolation of particle intensities for various geometries employed in emulsion work are given. Some discussion of geomagnetic effects is given and data are presented showing that the earth’s shadow cone is not appreciably present at a geomagnetic latitude of 40o.
