Abstract

The interference between single-photon and two-photon ionization has been observed for electrons ejected in the direction n from the photomultiplier cathode exposed simultaneously to the picosecond pulse of a Nd laser E_ω and its second harmonic E_2ω. The change of the phase difference of such interference was measured for the switch of the polarizations from E_ω∥n, E_2ω,∥n to E_ω⊥ n, E_2ω∥n.
