Abstract
Traditional muon avoided-level-crossing measurements use "integral counting" analysis, which results in a simple 1-D spectrum with resonance lines. At pulsed muon facilities, the time spectrum (TD-ALC) is available "for free" so it should be analysed to extract all relevant information. An ALC line corresponds to resonant transfer of polarisation back and forth between the muon and the other spins in a radical, and this oscillation is often at a convenient frequency of order 1 MHz. Following the oscillation frequency through just one Δm = 0 line can give the hyperfine constants for both the muon and nucleus and the gyromagnetic ratio for that nucleus.
