摘要

Neutral fragments of methane were performed using femetoeecond laser at an intensity of 1013-14 W/cm2. A new mechanism of neutral dissociation is proposed in this work. The methane molecule is excited to super-excited states, in which it would dissociate into neutral fragments. We made Morse type potential energy surfaces for the super-excited molecules. Furthermore, we investigated the dissociation dy-namics of the super-excited states by using quasi-classical trajectory (QCT) method. The results thus interpret the neutral dissociation of the methane molecule in the ultra-fast laser pulse.
