“…Coffin et al (1958) used the muon-decay asymmetry to detect the resonant absorption of radio-frequency (rf) energy in an early measurement of the muon magnetic moment. In this experiment a 12-kV ringing pulse was triggered upon detecting a stopped muon with a rate of 20 events/min.…”

Positive muons implanted into diamond and zincblende-structured semiconductors often form hydrogenlike paramagnetic muonium (ju + -e~) states whose characteristics can be investigated with the "muon spin rotation" (/xSR) technique. In contrast to the case of hydrogen, which is not known to form a paramagnetic state in semiconductors, two coexisting types of muonium states are seen. "Mu" with a large isotropic hyperfine interaction, and "Mu*" with a small [lll]-axially symmetric hyperfine interaction. Both "spectroscopic" properties of these states, such as the electronic g factors and the nuclear hyperfine interactions, and "dynamic" properties, such as their diffusion rates and their rates of interconversion, are accessible with /iSR. Direct information about the site of the muonium states is available usin'g the channeling effect of the positron from muon decay in a crystalline host. The techniques for probing semiconductors with positive muons are described in this review, and the results they have provided to date are critically discussed. The considerable amount of theoretical work that has been invested in microscopic models of Mu and Mu* is also summarized. CONTENTS

“…This was quickly followed by an improved measurement in Liverpool, which reported g µ = 2.004 ± 0.014 and is notable for an early example of the "wiggle plot" that is a feature of later storage-ring experiments [30]. Subsequent measurements by Garwin and collaborators led by 1960 to the determination a µ = 0.001 13 +0.000 16 −0.000 12 , in good agreement with the contemporaneous prediction, a th:1960 µ = 0.001 16 [31]. Over nearly two decades, three elegant storage-ring experiments at CERN greatly advanced both technique and precision.…”

“…First demonstrated by Coffin et al [1] in 1958, the application of RF methods to µSR experiments has become increasingly common following a comprehensive study at KEK in 1981 [2]. Recently, a number of groups have used resonance methods analogous to continuous-wave NMR to investigate topics including the dynamics of chemical reactions [3], final state determination [4,5], semiconductors [6][7][8][9][10] and iron [11].…”

Radio-frequency μSR experiments at the ISIS pulsed muon facility

This paper explores the use of pulsed radio-frequency (RF) techniques to remove the frequency limitations imposed on conventional transverse muon spin rotation (µSR) experiments at a pulsed muon source by the finite muon pulse width. The implementation of the 90' pulse technique is demonstrated by observing the free precession signal of diamagnetic muons implanted in polythene, the change in signal amplitude as a function of RF pulse length is plotted and the precise condition for a 90' pulse determined. The technique is evaluated by comparing measurements made using conventional spin rotation experiments to those employing pulsed RF methods. The potential for applying standard NMR multiple-pulse methods to the µSR experiment is considered and the use of two-pulse RF sequences (90 0 0-r-90° and 90°-r-180°) to form a muon spin echo demonstrated.
