State and Angular Resolved Electron Capture in a Merged-Beams Apparatus

An important feature of the merged beams technique is that the heat of a reaction in the center of mass frame is kinematically amplified when transformed to the laboratory frame. A multi-grid energy analyzer is used in a merged beams apparatus to study state selective cross sections and angular distributions for electron capture between multicharged ions and atomic D at eV/u collision energies. Product D{sup +} energy spectra are measured for Si{sup 4+} + D at collision energies 3.6 eV/u to 98.6 eV/u, and for O{sup 5+} + D at 17.1 eV/u. Comparison is made to state selective and angular scattering calculations where possible
