We identify peaks in the forward direction as arising from elastic collisions and those in the backward direction as from charge transfer. We show that the total cross section follows a semiclassical expression over a large range of energies and that the resonant charge transfer may be characterized by four energy regimes: an s-wave regime at ultralow energies, a modified Langevin regime at low energy, a Langevin regime at medium energy, and an “exchange” regime at high energy. We find large variations between the different isotopes for the two lowest-energy regimes and very little variation for the two highest-energy regimes. Our results are consistent with recent measurements. en_US dc.description.sponsorship Astronomy en_US dc.language.iso en_US en_US dc.publisher American Physical Society en_US dc.relation.isversionof doi:10.1103/PhysRevA.80.030703 en_US dash.license LAA dc.title Scattering of $$Yb$$ and $$Yb^+$$ en_US dc.type Journal Article en_US dc.description.version Version of Record en_US dc.relation.journal Physical Review A en_US dash.depositing.author Zhang, Peng dc.date.available 2011-09-23T18:01:59Z
