Title: Angular-momentum-dependent Fano profiles in excited zinc atoms

Abstract

The Fano-equivalent profiles of two negative-ion resonant states have been observed in the integrated Stokes parameters of 636.2 nm photons emitted from the 3d{sup 10}4s4d {sup 1}D{sub 2} state of zinc. These profiles reflect the effects of electron exchange and the spin-orbit interaction via the angular-momentum-dependent properties of the alignment and orientation Stokes parameters. The resonant states have energies of 10.98{+-}0.02 eV and 11.33{+-}0.02 eV and widths of 0.25{+-}0.03 eV and 0.33{+-}0.05 eV, respectively, and are bound to an excited atomic state with a 3d{sup 9} core hole. The lower-energy resonance shows a strong spin-orbit interaction whereas the higher-energy resonance shows negligible spin-orbit interaction.
