Attosecond angle-resolved photoelectron spectroscopy.
We report experiments on the characterization of a train of attosecond pulses obtained by high-harmonic generation, using mixed-color (XUV+IR) atomic two-photon ionization and electron detection on a velocity map imaging detector. We demonstrate that the relative phase of the harmonics is encoded both in the photoelectron yield and the angular distribution as a function of XUV-IR time delay, th...
متن کاملAttosecond photoelectron spectroscopy of metal surfaces.
Recent attosecond-streaking spectroscopy experiments [A. L. Cavalieri, Nature (London) 449, 1029 (2007)10.1038/nature06229] using copropagating extreme ultraviolet (XUV) and infrared (IR) pulses of variable relative delay have measured a delay of approximately 100 attoseconds between photoelectrons emitted by a single XUV photon from localized core states and delocalized conduction-band states ...
متن کاملAttosecond time-resolved photoelectron spectroscopy of surfaces
We discuss streaking time delays for photoemission from solid model surfaces as a function of the degree of the initial-wave-function localization and including the dynamical plasmon response to the motion of the photoelectron.
متن کاملSecondary electron cascade in attosecond photoelectron spectroscopy from metals
Synopsis In a recent attosecond photoelectron spectroscopy experiment from a metal surface [A. L. Cavalieri et al. Nature (London) 449, 1029 (2007)] a tail of unexplained low-energy electrons was measured. These electrons are shown to be due to electron-electron scatterings as the photoelectrons leave the metal. We develop a model for single scattering and a model based on cascade theory to des...
متن کاملPhotoelectron spectrometer for attosecond spectroscopy of liquids and gases.
A new apparatus for attosecond time-resolved photoelectron spectroscopy of liquids and gases is described. It combines a liquid microjet source with a magnetic-bottle photoelectron spectrometer and an actively stabilized attosecond beamline. The photoelectron spectrometer permits venting and pumping of the interaction chamber without affecting the low pressure in the flight tube. This pressure ...
