The momentum spectrum was measured with a magnetic spectrometer for cosmic particles incident vertically and at 68' zenith angle, in the range 2 to 70 Bev/c. The apparatus discriminated strongly against all particles but muons. The vertical muon spectrum was found to be in good agreement with the results reported by Pine et al., and by Ashton et al. No comparable data at 68 deg were previously published. Assuming muon creation to occur entirely through pion decay, a single pion production spectrum accounted for the muon spectra at both zenith angles. The muon positive excess at energies of 8 to 50 Bev was also obtained. The results, while in general agreement with those of other workers, confirmed the expected tendency for the positive excess to decrease with energy. (auth)
