Abstract
We report an experimental and theoretical investigation of low-energy electron scattering from 138Ba atoms prepared in the metastable 3D2 and 1D2 levels by laser-optical pumping. Differential cross sections were measured for excitation out of these metastable levels to a variety of higher-lying levels at electron-impact energies of 10, 20 and 36.7 eV. A comparison of experimental data with the results of theoretical approaches using the unitarized distorted-wave approximation and the convergent close-coupling scheme is given.
