| contents | Theoretical Study of the Dynamic Stark Effect on Dissociation of CsI Yonghua Zhu Peng Song Fengcai Ma Física, Astronomía y Matemáticas Wave Strong field Femtochemistry packet dynamics Photoelectron spectrum The influence of the dynamic Stark effect on the dissociation of CsI is theoretically studied by the time- dependent wave-packet method. After a pump pulse induces a dissociating wave packet that propagates through both the ionic channel X0+(Cs+(1S0)+I+(1S0)) and the covalent channel A0+(Cs(2S1/2)+I(2P3/2)), a Stark pulse is applied to control the diabatic-dissociation dynamics. The first-order non-resonant non-perturbative dynamic Stark effect gives control over the break up, the dissociation probabilities in the two channels being controlled by the delay between the pump and Stark pulses. With a 720-fs delay, the dissociation probability through channel A is greatly enhanced. 2014 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46431122001 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.2-3 Vol.44 |
