Abstract

The S-matrix theory is developed to study the non-sequential double ionization (NSDI) of diatomic molecules N2 and O2 in intense field. It is shown that electronic structures influence the NSDI process of molecules. Comparing to N2, a suppression effect of NSDI of molecule O2 is found and it can be explained by the difference between the angular distributions of the first ionized photoelectrons of N2 and O2. The ratios of NSDI rate to single ionization rate are also obtained and are consistent with the experimental observation qualitatively.
