The longitudinal spin polarization in a μ + ‐spin‐resonance experiment is calculated for positive muons diffusing to traps in a metal foil of finite thickness. General expressions are given for the shape of the resonance lines of freely moving and of trapped muons as a function of foil thickness, rf amplitude, trapping probability, and of the local magnetic fields and relaxation rates Γ 1 , Γ 2 of the free and trapped muons.
