THE MOMENTUM SPECTRUM OF COSMIC RAYS AT A DEPTH OF 38 METRES WATER EQUIVALENT UNDERGROUND

Journal Article · · Proc. Roy. Soc. (London)
A direct determination was made of the cosmic-ray spectrum underground at a depth of 38 m.w.e. under Castle Rock, Nottingham. The spectrum is based on measurements of 1010 particles traversing a magnetic spectrograph having a maximum detectable momentum of 8 Bev/c. By comparing this spectrum with the ground-level spectrum the energy loss of fast mu -mesons in penetrating the 38 m.w.e. of rock was determined. It is shown that the energy loss for mu -mesons in the momentum range 7 to 15 Bev/c is as expected by theory, the collision process being responsible for most of the loss. (auth)
