✦ Synopsis
Complex formation via translation-to-vibration energy exchange is investigated in the H' +O, collisional system. The study is undertaken in the quanta1 infinite order sudden approximation framework using a basis of 14 vibronic states associated with the electronically elastic H+ +O,( v) channels. For collision energies below the first vibrational excitation channel, Feshbach as well as shape resonances are found whose lifetimes are generally smaller than a rotation period of the Oz molecule. The total elastic cross-section, at a fixed relative angle, as a function of energy shows numerous structures that can be analyzed in terms of the found resonances.
