Abstract:

 Using the quasiclassical trajectory method, the influences of the vibrationally excited state of reactant cluster in Si4+Si3 have been studied. The reactive cross sections for each channel in reaction Si4+Si3, Si4(n1 =5)+Si3 and Si4+Si3(n1’ =5) have been calculated and the results show that the cluster(s) in the vibrationally excited state(s) is in favor of the deeply inelastic collision. One can control the product channels by means of controling the vibrational excitation of the reactant channel.

Key words: Si_n cluster, Clusters reactive dynamics, Reactive cross section
