Absolute and ratio measurements of the polarizability of Na, K, and Rb with an atom interferometer
ORAL
Abstract
We present absolute and ratio measurements of the ground state electric dipole polarizability of sodium, potassium, and rubidium using a Mach-Zehnder atom interferometer with an electric field gradient. The uncertainty of each absolute measurement is less than 1.0\% and the uncertainty of each ratio measurement is 0.3\%. Our measurements serve as improved tests of atomic structure calculations.
