Abstract: | A computation is carried out for light-induced shifts in the frequency of a multiphoton radiooptical SHF resonance in alkali
atoms on the basis of the quantum formalism of spherical tensors. The components of a light-induced shift in frequency at
magneto-independent 0–0– and 1,–1-transitions in87Rb atoms under the conditions of isotopic filtration of the resonance light of pumping are calculated. The difference between
the temperatures of a filter cell is discovered at which the point of zero shift in the frequency of radiooptical resonance
is attained. The components of the light-induced shift of frequency in optically oriented87Rb and133Cs atoms are compared in the absence of collisional reorientation in excited state. The prevailing role of the tensor component
of light-induced shift in pumping by the D1-line of a head doublet and the effect of the orientational dependence of the frequency of a multiphoton resonance on change
in the sign of the pumping source radiation polarization are noted.
