We have measured the ratio R of the vector ac Stark effect (or light shift) in the 6S1∕2 and 5D3∕2 states of a single trapped barium ion to 0.2% accuracy at two different off-resonant wavelengths. We earlier found R=\ensuremathΔS∕\ensuremathΔD=\ensuremath-11.494(13) at 514.531\phantom\rule0.3em0exnm where \ensuremathΔS,D are the vector light shifts of the 6S1∕2 and 5D3∕2 m=\ifmmode±\else\textpm\fi1∕2 splittings due to circularly polarized light, and now we report the value at 1111.68\phantom\rule0.3em0exnm, R=+0.4176(8). These observations together yield a value of the ⟨5D\ensuremath\Verter\ensuremath\Vert4F⟩ matrix element. Also, comparison of our results with an ab initio calculation of dynamic polarizability would yield a test of atomic theory and improve the understanding of atomic structure needed to interpret a proposed atomic parity violation experiment.
