Experimental constraints on the polarizabilities of the 6s2 1S0 and 6s6 p 3P0o states of Yb

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 6s(2) S-1(0) ground state, we find the polarizability a to be constrained to 134.4 < alpha <= 144.2 in atomic units while for the 6s6p P-3(0)o excited state, we find 280.1 < alpha <= 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.
