Muonium in synthetic diamond

Behavior of the muonium in two polycrystalline CVD diamond samples and in the sample composed of few single-crystal synthetic diamonds was studied by transverse-field μSR measurement. The hyperfine interaction constants for muonium in the synthetic samples are in agreement with those in natural diamond. The relaxation rate of muon spin and the amount of the MuT fraction in the synthetic samples are close to those observed in IIa- and IIb-type single-crystal natural diamonds.

► The hyperfine interaction in muonium which imitates hydrogen in synthetic diamond was studied for the first time.
► The probability for muonium to be localized at different sites in crystal lattice in synthetic diamond was measured.
► The difference in the results for natural and synthetic diamonds is discussed.
