摘要：
We study strong-field dissociative molecular double ionization with momentum-resolved quadruple coincidence measurements, measuring the two electrons and two ionic fragments produced with a coincidence velocity map imaging apparatus. We contrast measurements for two different molecules. In one case, our measurements reveal anticorrelation in the momentum for the two electrons. In the other, we find no anticorrelation, indicating differences in the underlying ionization dynamics.
