摘要：
Transverse-field mu SR spectroscopy was used to study the behaviour of positive muons implanted in polycrystalline chemical-vapour-deposited (CVD) diamond. Measurements were made at sample temperatures of 10 K, 100 K, and 300 K at a magnetic field of 7.5 mT to study the behaviour of the ''normal'' (isotropic) muonium state (Mu(T)) and the diamagnetic states (mu(d)) 10 K and 300 K at the so-called ''magic field'' of 407.25 mT to study the anomalous (bond-centred) muonium state (Mu(BC)) and mu(d). The absolute fractions of the muonium states in the CVD diamond are observed to be close to those in high-quality natural type-IIa single crystal diamond.
