“…General formulae for the cross sections and rate constants of electron-impact resonant DE process are derived with explicit dependencies on the electron energy, and the gas, T, and electronic, T e , temperatures. Together with our previous results [39,59,60], the approach gives a unified treatment of the contributions from the DE and DR processes to the total rate of molecular ion breakup.…”

“…To account for this, we represent the rate of the DR as α dr (T e , T ) = α dr low (T e , T )+ α dr Ry (T e , T ), where α dr low (T e , T ) is an effective rate constant of the dissociative capture to low-lying xenon states. α dr low (T e , T) was dissected from the experimental data using a recently developed approach [60] based on the effective state model and the least square interpolation in the low T e 1000 K range.…”

We have developed a semiclassical approach to the description of resonant dissociative excitation of a molecular ion induced by collisions with plasma free electrons and accompanied by the non-adiabatic transitions between its different electronic terms. It is based on the quasistatic treatment of nuclear particles relative motion in a molecular ion combined with the approximation of a quasicontinuum for rovibrational states. We have derived the semianalytic expressions for the Boltzmann-averaged cross sections, , and rate constants, α de(T, T e), of this process. The resulting expressions for and α de(T, T e) with explicit dependencies on the electron energy, ɛ, the gas, T, and electron, T e, temperatures are valid when the thermal energy k B T exceeds the value of the lowest vibrational quantum, ℏω e, of a molecular ion. The theory developed is applied to studying the resonant dissociative excitation of homo-nuclear , and ions as well as the hetero-nuclear rare gas ions RgXe+ (Rg = Ne, Ar, and Kr) with significantly different values of the dissociation energy. The efficiencies of the electron-impact dissociative excitation process and dissociative recombination leading to the population of the Rydberg states are compared. Our results of calculations are in good agreement with the available experimental data.
