Abstract: | We derive a formula using closed-orbit theory for the photodetachment cross-section of H- in the presence of a static electric field when there is an arbitrary angle θL between the laser polarization direction and the static electric field. This formula generalizes the previous result for
laser polarization parallel to the static electric field, the effect of laser polarization direction appears as a factor cos2(θL) in the amplitude of the oscillation. A photodetachment cross-section formula valid above and below detachment threshold
is proposed. |
