StandardSC¶
Description¶
Sinusoidal function damped with Gaussian relaxation and a non-decaying oscillation:
where,
\(A_\text{bg}\) is the amplitude of the background field oscillation,
\(A_0\) is the amplitude of the decaying oscillation due to internal field,
\(\omega_\text{SC}\) (rad/s) is the angular frequency of internal field,
\(\omega_\text{BG}\) (rad/s) is the angular frequency of background field,
\(\sigma\) is the depolarization rate,
and \(\phi\) is the phase.
The relationship between \(\omega\) and magnetic field B is given by:
where,
\(\gamma_\mu\) is the gyromagnetic ratio of muon.
