It is shown that the P- and T-noninvariant interactions of atoms with photons lead to P- and T-noninvariant dichroism and rotation of the spin of the atoms (nuclei) passing through a region occupied by light.

T. Kampschulte, et al., in Phys. Rev. Lett., {\bf 105}, 153603 (2010) observed surprising for them a strong cooling effect in the presence of resonance vertical probe Raman laser beam. However, this cooling effect is a simple and natural consequence of the fundamental property of quantum physics: time reversal noninvariance.

The effect of P-odd atomic spin rotation in a laser wave with a finite linewidth is considered. We have shown that laser linewidth is the major source of relaxation, limiting the available value of the spin rotation angle. A project of an atomic beam experiment to observe P-odd atom spin rotation is proposed. It is shown that such an experiment would provide better sensitivity than that of the previous ones.
