High-resolution photoassociation spectroscopy of ultracold Cs2 long-range 0g- state：The external well potential depth

doi:10.1088/1674-1056/23/1/013301

Abstract High-resolution photoassociation spectroscopy is reported using a modulation spectroscopy technology in a cesium atomic magneto-optical trap. The two lowest vibrational levels have been experimentally observed which have been theoretically predicted in [Phys. Rev. A 75 052501 (2007)]. A new potential curve is obtained by using the Rydberg–Klein–Ress method with a well depth of -82.384±0.026 cm^-1, which is deeper than the result of previous experiment (-77.909 cm^-1) and the theoretical prediction (-81.6445 cm^-1).

Keywords: ultracold molecules photoassociation trap-loss spectroscopy potential depth
