Abstract
The $X^{1}\Sigma_{g}^{+}(1,J^{'''})\to A^{1}\Sigma_{u}^{+}(1,J^{\prime\prime})\to 3{^{1}}\Sigma_{g}^{+}(0,J^{\prime})\to nl^{1}\Lambda_{u}^{+}(0,J)$ transition scheme is used to study high n sodium dimer rydberg states. The spectrum is simplest when the intermediate state has $J' = 0$ which implies $J = 1$. Analysis of our data yield an ionization potential of $39478.13\pm 0.03cm^{-1}$, implying a molecular ion dissociation energy of $D_{0}^{0}(Na_{2}^{+})=7914.19\pm 0.03cm^{-1}$. The same transition scheme can be used to detect ultracold ground state molecules $Na_{2}(v=0,J=0)$ and to produce ultracold ground state molecule ions $Na_{2}^{+}(v^{+}=0,N^{+}=0)$.
