摘要：

A search for muon trapping at lattice defects in proton-irradiated aluminum and copper in a μSR-experiment is reported. Thin foils have been irradiated at 77 K with 4 MeV protons to a total dose of 2 × 1015 particles cm-2 resulting in a defect concentration of approximately 80 ppm for Cu and 30 ppm for Al. No trapping of muons is observed below 300 K in both targets. An upper limit for the trapping rate of 0.5 μs-1 is derived. © 1978.
