| Resumen en inglés | 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 +(1 S 0) + I +(1 S 0)) and the covalent channel A0+(Cs(2 S 1/2) + I(2 P 3/2)), 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 |
