Quantum-mechanical effects in the mechanism of positronium spin conversion by FeCl2 in water-giycerol mixtures have been demonstrated by measurements of the rate constant of the process as a function of viscosity over the range 0.7-466 cP. Apparently these effects are due to the tunnelling of the positronium atom (Ps) as a whole from some trap to the corresponding level of the complex (PsFe2+). Similar effects have not been observed for oxidation of Ps by K2Cr2O7.
