In this paper we report the measurement of the frequency Stark shift of the ground-state hyperfine transition of 133Cs observed in a vapor cell through a Λ excitation scheme. The measured value of the quadratic Stark coefficient is k=(−2.05±0.04)×10−10 Hz∕(V∕m)2 when the electric field is perpendicular to the quantization axis. A comparison with the values previously reported in literature is given in view of its interest for the evaluation of the blackbody radiation shift in the primary frequency standards.

Abstract
In this paper we report the measurement of the frequency Stark shift of the ground-state hyperfine transition of 133Cs observed in a vapor cell through a Λ excitation scheme. The measured value of the quadratic Stark coefficient is k=(−2.05±0.04)×10−10 Hz∕(V∕m)2 when the electric field is perpendicular to the quantization axis. A comparison with the values previously reported in literature is given in view of its interest for the evaluation of the blackbody radiation shift in the primary frequency standards.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
