“…Our experiments are performed using Cs atoms prepared in |F = 3, m F = +3 in a magnetic field of 23.4(1) G. We calculate the polarizability including hyperfine structure following the methods described in detail elsewhere [45,48,51]. Below we summarize the main results.…”

“…There are a number of theoretical predictions for λ 0 [24,46,48]. However, only one of these theoretical values takes into account the hyperfine structure of the atoms [48] and gives a predicted tune-out wavelength of 880.20(5) nm. Our measured tune-out wavelength agrees well with this result.…”

“…Previous experiments have directly measured tuneout wavelengths, using linearly polarized light, for different alkali-metal atoms, including Li [38,39], K [26,40], and Rb [25,33,37,41], as well as for other atomic species, including He [42], Sr [31], and Dy [43] and also for ground-state NaK molecules [44]. However, despite many theoretical studies of 133 Cs polarizability [45][46][47][48], so far no measurements of 133 Cs scalar tune-out wavelength have been performed. And yet 133 Cs atoms are used in a wide range of applications including the definition of the second [49], the search for variations in fundamental constants, and tests of the standard model.…”

We perform a measurement of the tune-out wavelength, λ 0 , between the D 1 , 6 2 S 1/2 → 6 2 P 1/2 , and D 2 , 6 2 S 1/2 → 6 2 P 3/2 , transitions for 133 Cs in the ground hyperfine state (F = 3, m F = +3). At λ 0 , the frequencydependent scalar polarizability is zero leading to a zero scalar ac Stark shift. We measure the polarizability as a function of wavelength using Kapitza-Dirac scattering of a 133 Cs Bose-Einstein condensate in a one-dimensional optical lattice, and determine the tune-out wavelength to be λ 0 = 880.21790( 40) stat (8) sys nm. From this measurement we determine the ratio of reduced matrix elements to be 1.9808(2). This represents an improvement of a factor of 10 over previous results derived from excited-state lifetime measurements. We use the present measurement as a benchmark test of high-precision theory.

“…When considering degeneracies of states only, this ratio is expected to be R = 2. However, including relativistic corrections, which are large for Cs compared to other alkali-metal atoms due to the large atomic mass, this ratio is reduced, with a theoretical value of R = 1.984(10) [48].…”

We perform a measurement of the tune-out wavelength, λ0, between the D1, 6 2 S 1/2 → 6 2 P 1/2 , and D2, 6 2 S 1/2 → 6 2 P 3/2 , transitions for 133 Cs in the ground hyperfine state (F = 3, mF = +3). At λ0, the frequency-dependent scalar polarizability is zero leading to a zero scalar ac Stark shift. We measure the polarizability as a function of wavelength using Kapitza-Dirac scattering of a 133 Cs Bose-Einstein condensate in a one-dimensional optical lattice, and determine the tuneout wavelength to be λ0 = 880.21790( 40)stat( 8)sys nm. From this measurement we determine the ratio of reduced matrix elements to be 9808(2). This represents an improvement of a factor of 10 over previous results derived from excited-state lifetime measurements. We use the present measurement as a benchmark test of high-precision theory.

Combining the multi-configuration Dirac-Hartree-Fock (MCDHF) methodand the model-QED approach, the wave functions, transition energies and hyperfinestructures constants for 2l, 3l states in Li-like Ne7+, Mg 9+, Al 10+, P 12+, Ar 15+ andCa 17+ ions are calculated. The effects of electron correlation, Breit interactions, nuclear recoil and quantum electrodynamics (QED) effects are analyzed in detail. Wefind that the contribution of the non-diagonal elements of the self-energy is significantfor the 2p1/2 → 2s 1/2 and 2p 3/2 → 2s 1/2 transitions. However, for the 3l → 2s 1/2transitions, the contribution of non-diagonal elements is small. The accuracy of thecurrently calculated hyperfine structure constants is expected to be within 1%.
