Abstract
- We report on the production of ultracold heteronuclear NaCs* molecules in a dual-species magnetooptical trap through photoassociation. The electronically excited molecules are formed below the Na (3S<subscript>1/2</subscript>) + Cs (6P<subscript>1/2</subscript>) dissociation limit. 12 resonance lines are detected using trap-loss spectroscopy based on a highly sensitive modulation technique. The highest observed rovibrational level exhibits clear hyperfine structure, which is detected for the first time. This structure is simulated within a simplified model consisting of 4 coupled levels belonging to the initially unperturbed Hund's case "a" electronic states, which have been explored in our previous work that dealt with the Na (3S<subscript>1/2</subscript>) + Cs (6P<subscript>3/2</subscript>) asymptote [W. Liu et al., Phys. Rev. A 94, 032518 (2016)]. [ABSTRACT FROM AUTHOR]
