The 300 ton cosmic ray spectrograph (MARS) has been used to measure the vertical momentum spectrum of cosmic ray muons in the momentum range 20-500GeVlc at sea level. The differential spectrum is well represented by the logarithmic polyi:omial p3 N ~= =)-0.524-iO.366 (Inp)--0.0445 (lnp)z+OGOOS (InpI3 where p is in Gev/c and N(p) is in s-l cm- * sr- ' (GeV/c)-'. 1.
