Contribution of the tensor component to the light shift of the rf optical microwave resonance frequency in rubidium vapor

We have calculated the tensor component of the light shift for the frequency of the rf optical microwave resonance on the magnetically independen 0−0 and 1, −1 transitions in rubidium-87 atoms under conditions of isotope filtering of the resonant pump light. We have observed a difference between the temperatures of the filter cell at which a zero frequency shift is achieved for the rf optical resonance for these transitions. We have noted that selective optical pumping on theD ₁ lines is advisable when using a two-photon microwave transition in rubidium vapor in applications.
