Dissociative ionization of NO in few-cycle intense laser fields: Effects of π-σ Electronic transition

Abstract

Dissociative ionization (DI) of NO in few-cycle intense laser fields was investigated by using the 3D momentum imaging method. It was found that the symmetry change in the outermost occupied molecular orbital upon the π-σ electronic transition is clearly reflected in the spatial anisotropy of the fragmention, N+.
