Modeling ultracold lithium ion-atom collision

Abstract

Accurate estimation of the scattering properties at the ultracold temperatures is challenging due to the demand for the precise knowledge of interactions between the colliding partners. We identify the aspects of interactions that play the defining roles in the scattering calculations. We compute potential energy curves for the 7Li+-7Li, X2∑g + and A2∑u +, and determine their collisional properties.
