    Abstract The dynamics of the various muon states (paramagnetic states muonium Mu and anomalous muonium Mu*, diamagnetic states μd) were studied by means of radio‐frequency μ+ spin resonance (RFμSR), longitudinal field‐quenching (LFQ), and transverse μ+ spin rotation (TFμSR) in an undoped high‐purity and a gallium‐doped germanium single crystal in the temperature range 3.5–320 K. In boron‐doped Si the influence of photo‐induced charge carriers leads to muon state dynamics which is fundamentally different from the one observed if majority carriers are generated thermally. LFQ measurements have been performed in the temperature range 55–320 K in order to study these dynamic processes.

    Notes:
    Abstract Longitudinal‐field μSR methods, e.g., radio‐frequency μ+ spin resonance (RFμSR), are well suited to investigate dynamic processes that destroy the phase coherence of the muon spin ensemble. Additional information on relaxation processes of the muon species under investigation is obtained from time‐differential (TD) data acquisition. In this paper we describe the set‐up of a TD‐RFμSR spectrometer installed at the ISIS pulsed muon facility at the Rutherford Appleton Laboratory (RAL, Chilton, UK). As an example, results of TD‐RFμSR measurements on muons in diamagnetic environment μd in a boron‐doped silicon sample under illumination at 55 K are presented.
