DampedBessel¶

Description¶

A bessel function with damped oscillation that could apply to incommensurate magnetic structures or spin density waves.

where,

$A_0$ is the amplitude of asymmetry,

$J_0(x)$ is the Bessel function of the first kind,

$\lambda_\text{T}$ is the damping of the oscillation,

$\lambda_\text{L}$ is the dynamic longitudinal spin relaxation rate,

$B$ (G) is the B-field,

and $\phi$ is the phase.
