概要 In order to study interactions between photons and a metal surface, a new laser photoionization apparatus was constructed and applied to photoionization of a Zr surface by one-photon or two-photon las...er ionization in air. The time profile of photocurrents consisted of two components. One short component was attributed to photoelectrons from the Zr surface and the other long one was explained as dueto O_2 anions formed by an electron attachment to O_2. The dependence of the peak voltage and the recovery time on the applied voltage between the Zr rod and a charged particle collector was measured.続きを見る
