After averaging the cos 𝜔 !)) 𝑡 𝑎𝑛𝑑 sin 𝜔 !)) 𝑡 terms in (11) and inserting the definition of 𝜃, we find an enhanced nuclear polarization Here we also expand the definitions of θ and ωeff. In a completely similar way we find that the component of the electron polarization along the effective field is reduced by an
