Query: Coordinate-space Faddeev-Hahn-type approach to three-body charge
  transfer reactions involving exotic particles   Low-energy muon-transfer cross sections and rates in collisions of muonic
atoms with hydrogen isotopes are calculated using a six-state close-coupling
approximation to coordinate-space Faddeev-Hahn-type equations. In the muonic
case satisfactory results are obtained for all hydrogen isotopes and the
experimentaly observed strong isotopic dependence of transfer rates is also
reproduced. A comparison with results of other theoretical and available
experimental works is presented. The present model also leads to good transfer
cross sections in the well-understood problem of antihydrogen formation in
antiproton-positronium collision.
