Depolarization ratios for anti-stokes Raman scattering from In and T1

An argon ion laser and metal halide arcs are used to measure the depolarization ratios for anti-Stokes electronic Raman scattering from indium and thallium atoms. A comparison with theoretical results obtained using different assumptions about the relative phases of radial matrix elements gives conclusive evidence about which relative phases are correct. This information is essential to make a calculation of nonresonant Raman scattering cross sections possible.
