High resolution photoassociation spectroscopy of the excited $c^3\Sigma_{1}^+$ potential of $^{23}$Na$^{133}$Cs
arXiv (Cornell University)(2023)
摘要
We report on photoassociation spectroscopy probing the $c^3\Sigma_{1}^+$ potential of the bi-alkali NaCs molecule, identifying eleven vibrational lines between $v' = 0$ and $v' = 25$ of the excited $c^3\Sigma_{1}^+$ potential, and resolving their rotational and hyperfine structure. The observed lines are assigned by fitting to an effective Hamiltonian model of the excited state structure with rotational and hyperfine constants as free parameters. We discuss unexpected broadening of select vibrational lines, and its possible link to strong spin-orbit coupling of the $c^3\Sigma_{1}^+$ potential with the nearby $b^3\Pi_1$ and $B^1\Pi_1$ manifolds. Finally we report use of the $v' = 22$ line as an intermediate state for two-photon transfer of weakly bound Feshbach molecules to the rovibrational ground state of the $X^1\Sigma^+$ manifold.
