Abstract
We have performed a type of Autler-Townes spectroscopy to locate a number of rovibrational hyperfine levels of the a ^3^ς+u potential, the lowest triplet potential of the Na2 dimer. The spectroscopy starts with the photoassociation of ultracold atoms in a magneto-optical trap. We have measured the binding energies of approximately 100 individual states spanning the vibrational levels Ņ=8-15 of this potential (binding energies up to 27 cm-1). We obtain a typical accuracy of 15 MHz and a typical resolution of {difference} 20 MHz, improving on the 10 GHz accuraxy and 30 GHz resolution previously available for the vibrational states ŅCitation
