Abstract. We have shown on a simple model that the anisotropy of collisions induced by a <pi>-polarized RF field may lead to the reduction of relaxation rate of the linear-polarized light observed along the axis of anisotropy. In the simplest case of j=1 of the excited state the difference with the isotropic case may reach 20% of the relaxation constant of alignment.
