Quantum dynamics of ultracold Li + CaF → LiF+ Ca chemical reaction
POSTER
Abstract
Calcium monofluoride is a prominent candidate for cold collision experiments due in part to its favorable Franck-Condon properties for laser cooling and magneto-optical trapping.
Recently, the first measurement of CaF + CaF inelastic collisions, loaded into optical tweezers, has been made. Investigation of magnetic Feshbach resonances in 6Li+CaF collisions and reactions of CaF and 6Li mixtures near quantum degeneracy are topics of current interest. In this work, we construct a global three-dimensional potential energy surface for the Li+CaF system and report preliminary results of quantum scattering calculations of the 6Li+CaF→ 6LiF+Ca chemical reaction. The reaction is characterized by an exoergicity of about 0.5 eV populating up to five vibrational manifolds, and a few hundred rotational levels of LiF, that are energetically accessible at a collision energy of 1 mK.
