Özet
Double differential cross sections for state-selective single-electron capture processes in Ar6+-He collisions have been measured at laboratory energies between 75 and 900 eV and scattering angles between 0 and 8 degrees. At the lowest energy, the zero-angle spectrum shows capture into Ar5+(4p) to be the most important channel. However,as the scattering angle is increased, a second peak appears at angles greater than or equal to 2 degrees and becomes more pronounced relative to the 4p capture channel. The energy spectra are interpreted qualitatively in terms of the reaction windows, which are calculated using the single-crossing Landau-Zener model Total and differential cross sections are also measured and compared with available measurements and calculations.
