摘要：

We consider high-order above-threshold ionization of polyatomic molecules by a strong laser field. An improved molecular strong-field approximation which takes into account the electron rescattering off the molecular centers is developed. The presented theory is applied to calculate the photoelectron energy and angular distributions for the ozone molecule. The obtained spectra exhibit pronounced minima, and this is explained as a three-point destructive interference of the rescattered electron wave packets.
