英文摘要:
We theoretically investigate the pulse duration dependence in the laser-induced dissociation of the molecular ion H-2(+) The simulation results show that the dissociation ratio can be split up into three regions with increasing duration of the external laser pulse, with a central wavelength of 228 nm, as a result of the electron capture of the vibrationally highly excited H-2(+) With the coupled equations of the 1 s sigma(g) and 2p sigma(u) states one can find that the pulse duration dependence in the photodissociation of H-2(+) is due to the different responses of the molecular dipole to the evolution time of the ultraviolet laser pulse.
