"Anomalous" temperature dependence of the rate of μ+-meson polarization relaxation in some normal metals
Mika'elyan A.L., Smilga V.P.
We obtain and solve equations that describe the "strange" behavior of the rate of relaxation of the polarization of μ+ mesons in a number of metals. A new mechanism of this phenomenon is proposed. It is shown that in Nb and Bi the experiment cannot be attributed to trapping of muons by the impurities, but agrees fully with the hypothesis of trapping in different pores. Experiments are considered which make it possible to explain unambiguously the nature of the "strange" relaxation in an actual metal.
