Abstract

On the basis of experimental results on neutron production by protons and muons, the total counting rate and the detected multiplicity spectrum normally recorded by a standard IGY neutron monitor are analyzed in terms of the components of the cosmic radiation at sea level. It is shown that approximately 93% of the detected neutrons are caused by neutron and proton interactions and that a definite relation exists between the detected multiplicity spectrum and the energy spectrum of nucleons at sea level. It is expected that time variations in the rates of the detected multiplicities will reflect the behavior of the primary energy spectrum of the cosmic radiation at energies up to the order of 200 Gev, and that this will be useful in the study of the various time-dependent phenomena of the cosmic radiation.
