Inelastic interaction induced by high-energy muons (6 GeV, 12 GeV) at low momentum-transfer in nuclear emulsion

Summary  Inelastic scattering of 6 and 12 GeV muons has been studied in Ilford K5 nuclear emulsions. For energy transfers greater than 150 MeV (for π muoproduction threshold) and a four-momentum transfer smaller than 0.1 (GeV/c)2, the cross-sections are respectively (11.1±1.4) μb/nucleon at 12 GeV and (6.8±0.9) μb/nucleon at 6 GeV. The ratios of the mean values of the longitudinal and transverse cross-sections are respectively 0.46±0.15 and 0.25±0.15. These values are very useful for a comparison between electron and muon.
