We report results of one electron capture by highly charged ions colliding with laser excited aligned Na*(3p). The 0 vi(10-->8) photon emission cross section after electron capture by the O6+ projectile is measured in the collision energy range 2-8 keV/amu. Effects of the Na*(3p) orbital alignment on the O VI(10-->8) emission are observed and found to be ''reversed'' as compared to the He2+ --> Na*(3p) collision system. Classical trajectory Monte Carlo calculations agree with the measured data and indicate that capture to states with n > 10, contributing to the O VI(10-->8) emission via cascades, plays a crucial role in the alignment cross sections.
