Title: Interferometric measurements of dynamic polarizabilities for metal atoms using electrically exploding wires in vacuum

Abstract

Measurements within 10% accuracy of the dynamic dipole polarizabilities {alpha}({lambda}) for five nonrefractory metal atoms (Mg, Ag, Al, Cu, and Au) at laser wavelengths of {lambda}=532 and 1064 nm are presented using electrical explosion of thin wires in vacuum and a novel laser probing integrated-phase technique. The technique is based on single-wavelength interferometry and does not require axial symmetry of the tested object. Theoretical prediction of {alpha}({lambda}) for wavelengths {lambda}=355, 532, and 1064 nm, as well as the static dipole polarizabilities {alpha}{sub st}, are also presented. An agreement within 20% was obtained between calculated data, recommended static polarizabilities {alpha}{sub st}, and the measured dynamic polarizabilities {alpha}(532 nm) and {alpha}(1064 nm)
