\(\renewcommand\AA{\unicode{x212B}}\)
Bessel function oscillation with Gaussian damp \(\frac{1}{3}\) component. Example: Spin Density Wave.
where,
\(N_O\) is the count at \(t=0\) ,
\(\sigma\) (MHz) is the Gaussian relaxation rate,
\(\omega = 2\pi \nu\) is the oscillating frequency,
\(\nu\) (MHz) is the oscillation frequency,
and \(\phi\) is the phase.
