GaussBessel

Description

Bessel function oscillation with Gaussian damp 13 component. Example: Spin Density Wave.

A(t)=A0(13+23J0(ωt+ϕ)e(σt)22)

where,

NO is the count at t=0 ,

σ (MHz) is the Gaussian relaxation rate,

ω=2πν is the oscillating frequency,

ν (MHz) is the oscillation frequency,

and ϕ is the phase.
