The Momentum Spectrum of Cosmic Ray Muons near Sea Level in the Momentum Range 0.4-10 GeV/<i>c</i>

Abstract

The momentum spectrum of muons in the vertical cosmic ray flux at Durham has been measured for the momentum range 0.4-10 GeV/c. The measurements are based on some 191 000 trajectories. The bias introduced by the condition that the particles should be unaccompanied has been studied and found to be small.
