Abstract : The final scientific report is presented on a comprehensive program planned to relate cosmic ray muon intensity measurements to theoretical calculations on the production and propagation of muons in the earth's atmosphere. Complete theoretical treatment of several basic models of muon production is given, including special attention to effects of the geomagnetic field on muon charge ratios at observation. The experimental method of obtaining absolute intensities is described in some detail. Experimental results on muon intensities and charge ratios at a variety of zenith angles and at moments above 3 GeV/c arc presented. (Author)
