The reorientation of the molecular adsorbates also induces a localization of the electron in the image state which is initially delocalized parallel to the surface. The localization phenomenon was proved by examining the emission angle dependence of the photoelectron spectra. It is concluded that the electrons in the delocalized state are trapped in the localized state at around 300 fs after the excitation, where the electron localization size is estimated to be 12 A. [Pg.62]
