Abstract:
Polarization measurements have been performed and emission spectra in the visible and near ultraviolet have been acquired for transitions between Rydberg states of slow, highly charged neon ions (Neq+, with q=10–5, and v≊0.09 a.u.), following electron capture from Na. Resolvable line splittings appear in those spectra for which the incoming projectile ions carry L-shell core electrons. The optical emission cross sections are much smaller for these ions and the radiation is significantly depolarized relative to those ions whose transitions are seen as structureless. These effects are attributed to the inhibition of Stark mixing by core interactions.
