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 p 3 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-'(More)
