英文摘要: A theoretical treatment of the photodissociation of the molecular ion Li-2(+) in one-color intense laser fields, using the time-dependent wave packet approach in a Floquet Born-Oppenheimer representation, is presented. Six electronic states 1,2(2)Sigma(g)+, 1,2(2)Sigma(u)+, 1 (2)Pi(g), and 1 (2)Pi(u) are of relevance in this simulation and have been included. The dependences of the fragmental dissociation probabilities and kinetic energy release (KER) spectra on pulse width, peak intensity, polarization angle, wavelength, and initial vibrational level are analyzed to interpret the influence of control parameters of the external field. Three main dissociation channels, 1 (2)Sigma(g)+ (m = -1), 2 (2)Sigma(g)+ (m = -2), and 2 (2)Sigma(u)+ (m = -3), are seen to dominate the dissociation processes under a wide variety of laser conditions and give rise to well separated groups of KER features. Different dissociation mechanisms for the involved Floquet channels are discussed. (C) 2011 American Institute of Physics. [doi:10.1063/1.3585645]
