Photoassociation spectroscopy of the B Π1 state of LiCs
We present an accurate potential energy curve of the B Π1 state in the LiCs molecule for which vibrational levels between v′=0 and v′=35 (bound by 11.4 GHz) were measured by photoassociation spectroscopy in an ultracold ensemble of L7i and C133s atoms. By the combination of conventional spectroscopi...

| Zusammenfassung: | We present an accurate potential energy curve of the B Π1 state in the LiCs molecule for which vibrational levels between v′=0 and v′=35 (bound by 11.4 GHz) were measured by photoassociation spectroscopy in an ultracold ensemble of L7i and C133s atoms. By the combination of conventional spectroscopic data of the B-X system and the new photoassociation measurements a very precise value of the dissociation energy of the ground state X Σ1+ of LiCs was determined to be D0=5783.495(5) cm−1. |
