Photoassociative Production Of Ultracold Heteronuclear Ybli∗ Molecules

Abstract

We report on the production of ultracold heteronuclear YbLi∗ molecules in a dual-species magneto-optical trap by photoassociation (PA). The formation of the electronically excited molecules close to dissociation was observed by trap loss spectroscopy. We find 4 rovibrational states within a range of 250GHz below the Yb(S01)+Li(P1/22) asymptote and observe isotopic PA line shifts in mixtures of Li6 with Yb174, Yb172, and Yb176. We also describe our theoretical ab initio calculation for the relevant electronic potentials and utilize it to analyze and identify the lines in the experimentally observed spectrum.
