Abstract
New results of spin polarization of both photoelectrons and Auger elec trons are reported after 5 p photoionization of free Ba atoms with cir cularly polarized light. A substantial polarization transfer from the spin polarized photons to the spin polarized photoelectrons and via th e hole state orientation to the spin polarized Auger-electrons is obse rved. The cross comparison of the results for photoelectrons and Auger -electrons allows a quantitative test of the assumed two step model wh ere both electron-emission processes occur in sequence.
