Sheldon, William R.2022-05-062022-05-06197413710718https://hdl.handle.net/10657/9095The multiple scattering of cosmic ray muons in a magnetic momentum spectrometer has been investigated both theoretically and experimentally. Theoretically, the multiple scattering theory of Moliere has been modified to account for observations made with magnetic spectrometers. Experimentally, 8000 muon events have been analyzed in the momentum region 2.5 GeV/c to 200 GeV/c for a target thickness of one meter of iron. Good agreement is found between the theoretical and experimental results.application/pdfenThis item is protected by copyright but is made available here under a claim of fair use (17 U.S.C. §107) for non-profit research and educational purposes.
