【 摘 要 】

Accurate state-to-state rovibrational inelastic collisional cross sections involving the smallest molecular anion as-tronomically detected with He(1S) based on two recently computed energy surfaces will be presented. A detailed comparison between the collisional findings provided either using a high-level of accuracy in the potential energy surface or taking advan-tage of the full-dimensional approach will be discussed.
