Abstract
Along the (100) direction of tungsten, interband transitions induced by circularly polarized light of energy lead to spin polarization of the excited conduction electrons. This is observed by measuring the spin polarization of the photoelectrons emitted from a cesiated crystal surface. The measured polarization values depend sensitively on the -, -, and -hybridization properties of the conduction bands. Excited-state lifetimes are obtained from the widths of the polarization structures.
