Experimental and theoretical study of the6d3/2polarizability of cesium

Abstract

We report polarizability measurements of atomic cesium's 6d 3/2 state. The scalar and tensor polarizabilities are determined from hyperfine-resolved Stark-shift measurements using two-photon laser-induced-fluorescence spectroscopy of an effusive beam. The resulting values are α 0 = −5310(180)a 3 0 and α 2 = 8650(260)a 3 0 . In addition, our measurements yield the hyperfine coupling constants A = 16.36(15) MHz and B = −0.7(8) MHz, which agree with previous measurements. We also present relativistic all-order calculations of both scalar and tensor polarizabilities. The resulting theoretical values, α 0 = −5686(121)a 3 0 and α 2 = 8750(82)a 3 0 , are in agreement with the present experimental results.

“…This electric-field-calibration method improves our polarizability resolution by a factor of 5 over our previous electromechanical method [17]. Figure 4 shows a typical dual fluorescence-absorption spectrum used for determining the Stark shift, in this case, for the 9s 2 S 1/2 (F = 4) state.…”

“…Any drift accumulated during one scan should, on average, be canceled by the subsequent scan in the opposite direction. In addition, our frequency-calibration technique (see below) has been demonstrated to effectively cancel out the laser-frequency drift [17].…”

“…It was further developed and was described in detail in Ref. [17]. The DL2 beam double passes an electro-optic modulator (EOM) driven at either 100 MHz (for 8s 2 S 1/2 measurements) or 120 MHz (for 9s 2 S 1/2 measurements).…”

Measurement of the Stark shift of the $6s^2S_{1/2} \rightarrow 7p^2P_{J} $ transitions in atomic cesium

“…The general principle of the measurement is similar to that of several other recent works [25][26][27][28]. We use the output of a single, narrow-band tunable laser source, which we split into two separate beams, labeled the reference and Stark beams in Fig.…”

Hyperfine structure of the7d2D3/2level in cesium measured by Doppler-free two-photon spectroscopy

“…Fendel et al [23] have recently used the optical-frequency comb spectroscopy technique to determine the absolute frequency of the 6s 2 S 1/2 → 8s 2 S 1/2 transition. Precision measurements of the hyperfine splitting of the 6d 2 D 3/2,5/2 have been carried out using two-photon spectroscopy and also by the stepwise excitation process [4,[29][30][31].…”
