Abstract
The differential polarizability, due to near-infrared light at 1126 nm, of the 27Al + 1S 0 → 3P 0 transition is measured to be Δα = 4πε 0 x (1.6 ± 0.5) × 10 -31 m 3, where Δα = α P - α S is the difference between the excited and ground state polarizabilities. This measurement is combined with experimental oscillator strengths to extrapolate the differential static polarizability of the clock transition as Δα(0) = 4πε 0×(1.5-0.5)×10 -31 m 3. The resulting room temperature blackbody shift of Δν/ν = -8(3)×10 -18 is the lowest known shift of all atomic transitions under consideration for optical frequency standards. A method is presented to estimate the differential static polarizability of an optical transition, from a differential light shift measurement.
