title: Threshold effects on angular distributions for multiphoton detachment by intense elliptically polarized light.
abstract: Unusual threshold effects are found theoretically in the frequency and intensity dependence of angular distributions produced by an elliptically polarized laser as well as in the elliptic dichroism parameter, which measures the asymmetry of the angular distribution.
