Abstract In a longitudinalμ +SR experiment on a high-purityα-Fe single crystal sphere magnetically saturated in a 〈 111 〉 direction damped oscillations (wiggles) were observed in a temperature range 30 mK to 600 mK and in a certain regime of applied magnetic fieldsB appl. Meassurements of the wiggle frequency as a function ofB appl give us directly the Fermi fieldB Fermi=(−1.13±0.02)T and the dipolar magnetic field ¦B dip ∥ ¦=(0.66±0.03)T.B dip ∥ was used to determine the prefactor in the Arrhenius law obeyed by theμ + hopping rate between 100 K and 1000 K. A comparision with the corresponding values for protons and deuterons suggests diffusion via the adiabatic mechanism.
