Dichroism in the electron-impact ionization of excited and oriented sodium atoms

Lower, Julian; Elliott, Anthony; Weigold, Erich; Mazevet, S; Berakdar, J.


Measurements are reported for kinematically complete electron-impact ionization collisions with oriented 3P sodium atoms excited from the ground state by right- and left-hand circularly polarized light. The measurements reveal a strong dependence of the ionization cross section on the helicity inversion of the exciting photon. This dichroic effect and the magnetic state resolved cross sections are described using the distorted-wave Born approximation and the dynamically screened Coulomb wave...[Show more]
