Experimental constraints on the polarizabilities of the 6s2 1S0 and 6s6p 3P0o states of Yb

Abstract
We utilize accurate experimental data available in the literature to yield bounds on the polarizabilities of the ground and first-excited states of atomic Yb. For the $6{s}^{2}{\phantom{\rule{0.16em}{0ex}}}^{1}\phantom{\rule{-0.16em}{0ex}}{S}_{0}^{}$ ground state, we find the polarizability $\ensuremath{\alpha}$ to be constrained to $134.4<\ensuremath{\alpha}\ensuremath{\le}144.2$ in atomic units while for the $6s6p{\phantom{\rule{0.16em}{0ex}}}^{3}\phantom{\rule{-0.16em}{0ex}}{P}_{0}^{o}$ excited state, we find $280.1<\ensuremath{\alpha}\ensuremath{\le}289.9$. The uncertainty in each of these values is 1.0. These constraints provide a valuable check for ab initio and semiempirical methods used to compute polarizabilities and other related properties in Yb.
