Modifying the photodetachment near a metal surface by a weak electric field

We show the photodetachment cross sections of H- near a metal surface can be modified using a weak static electric field. The modification is possible because the oscillatory part of the cross section near a metal surface is directly connected with the transit time and the action of the detached ele...

More Information
Summary:We show the photodetachment cross sections of H- near a metal surface can be modified using a weak static electric field. The modification is possible because the oscillatory part of the cross section near a metal surface is directly connected with the transit time and the action of the detached electron closed-orbit which can be changed systematically by varying the static electric field strength. Photodetachment cross sections for various photon energies and electric field values are calculated and displayed.
