Abstract

Co$^+$Ne was generated via laser vaporization in a pulsed supersonic expansion source, mass selected, and analyzed by visible photodissociation spectroscopy. An electronic band system was observed with an origin beginning at 13503 cm$^{-1}$. A progression of peaks beginning from the origin until the convergence limit can be seen, corresponding to the vibrational bands in the excited state of Co$^+$Ne. The excited state constants (we ??=124 cm$^{-1}$) were determined and the electronic cycle leads to a ground state binding energy (D$_0$ ? =948 cm$^{-1}$). The ground state binding energy can be compared to other rare gas binding energies, which is correlated to the polarizability of the rare gas.
