Hyperfine analysis of the high resolution features in the photo association spectrum of trapped Na atoms
We have carried out an analysis of the hyperfine structure of the molecular states of the Na{sub 2} molecule that correlate to the 2P{sub 3/2}+{sup 2}S separated atoms. We have calculated the adiabatic molecular potentials for the total angular momentum states, including nuclear spin, and the line strengths for optical coupling to the {sup 2}S+{sup 2}S ground state. The recently observed high resolution photoassociative ionization spectrum of trapped Na, a progression of sharp features extending up to 100 GHz detuning to the red of the Na {sup 2}S(F=2){yields}{sup 2}P{sub 3/2}(F=3) resonance transition, is explained as a free-bound-free molecular spectrum exhibiting sharp structure due to resolved hyperfine structure of the vibrational levels of the 1{sub g} state of the Na{sub 2} molecule. This is an example of high resolution photoassociation spectroscopy of ultracold atoms, making an ionic instead of a neutral molecule.
