Photoassociative creation of 6Li-40K molecules in a magneto-optical trap — •Armin Ridinger, Saptarishi Chaudhuri, Thomas Salez, Ulrich Eismann, Frédéric Chevy, and Christophe Salomon — Ecole Normale Supérieure, 24, rue Lhomond, 75005 Paris, France
The recent realization of gases of ultra-cold molecules in their vibrational ground state has opened a new frontier in atomic physics. However, efficient atom-molecule conversion by photoassociation (PA) requires a precise knowledge of the molecular potential under study. In this talk I will report on a preliminary study of photoassociation spectroscopy of 6Li- 40K in a magneto-optical trap. In particular we observed more than 40 clearly resolved rovibrational levels of the electronically excited LiK-molecule within 350 GHz below the 42P3/2 atomic limit of 40K allowing for an accurate determination of the interatomic potential parameters.
