| Abstract: | Strongly hydrogen-bonded diamagnetic “FμF” centres are formed by theμ
+ in a wide variety of fluoride crystals. Hydrogen atoms are expected to form similar “FHF” complexes. Through the “motional narrowing” of the zero-field muon relaxation function in NaF, we have observed an Arrhenius
temperature dependence of the dissociation rate of theFμF complex, yielding a binding energy of 1700 (200) K for theμ
+ in theFμF centre. |
