Analysis of polarizability measurements made with atom interferometry

We present revised measurements of the static electric dipole polarizabilities of K, Rb, and Cs based on atom interferometer experiments presented in [Phys. Rev. A 2015, 92, 052513] but now re-analyzed with new calibrations for the magnitude and geometry of the applied electric field gradient. The resulting polarizability values did not change, but the uncertainties were significantly reduced. Then, we interpret several measurements of alkali metal atomic polarizabilities in terms of atomic oscillator strengths f_ik, Einstein coefficients A_ik, state lifetimes τ_k, transition dipole matrix elements D_ik, line strengths S_ik, and van der Waals C₆ coefficients. Finally, we combine atom interferometer measurements of polarizabilities with independent measurements of lifetimes and C₆ values in order to quantify the residual contribution to polarizability due to all atomic transitions other than the principal ns-np_J transitions for alkali metal atoms.
