摘要：

Complete sets of direct electron-impact cross sections of vibrationally excited D2(v) molecules have been calculated by using a semiclassical approach. Calculated cross sections for dissociation, dissociative ionization, ionization and vibrational excitation according to the so-called E-V process show a decrease of threshold energy with increasing vibrational quantum number v of the target and a corresponding increase of the maximum cross sections. This last result is true for transitions to completely repulsive states (i.e. dissociation and dissociative ionization) while an intricate trend of maximum cross sections as a function of v is observed in the other cases. © 1990.
