Laser-induced dissociative recombination of carbon dioxide

The paper investigates the laser-induced dissociation recombination process of carbon dioxide. The coincidence measurements of all involved particles show that one electron can recombine to one of the two ionic fragments during the dissociative double ionization of carbon dioxide in a strong laser field. Photoelectron momentum distributions measured in experiments further reveal that the second ionized electron has much higher recombination probability than the first ionized electron. The results may trigger further experimental and theoretical studies on electron recombination during laser-induced molecular reactions.
