Summary The momentum spectra and charge ratios of cosmic-ray muons at sea level have been determined in the range 0.3–26 Gev/c at the equator (vertical cutoff rigidity Pc = 14 Gv) and at Kiel (Pc = 2.3 Gv). The measurements have been performed by means of a magnetic spectrograph using spark-chamber technique. There is a significant difference between the spectra for momentums smaller than 1 Gev/c; however, there is agreement as far as the charge ratios are concerned. The total latitude effect amounts to 15%.
