We determine the static values of the scalar and tensor dipole polarizabilities of the ground, 6s6p^3P0~o, and 6s6p^3P1~o states of the Yb atom. These results can be useful in many experiments undertaken using this at...
A transition or rare-earth metal is modeled as the atom immersed in a jellium at intermediate electron gas densities specified by? rs=4.0. The ground states of the spherical jellium atom are constructed based on the H...
