Abstract : We report results from a new atomic physics program using the Argonne PII ECR ion source which is being built as part of the upgrade of the Argonne Tandem-Linear Accelerator ATLAS. Our initial experiments have been aimed at studying state-selective electron capture in ion-atom collisions using the technique of Photon Emission Spectroscopy. We are extending existing cross section measurements at low energy < 15 keV-amu to higher energy taking advantage of the fact that the Argonne source is on a 350-kV high-voltage platform. Experiments have included measurements of capture cross sections for O6+ and O7+ on He and H2 targets in the energy range from 1-105 keV-amu. We also present UV spectra obtained in collisions of O6+, O5+ and N5+ on a sodium target.
