Dynamics Of Multiply Charged Ion-atom Collisions: U³²⁺+Ne

Measurements and calculations are presented for the mean recoil-ion energies of Nei+ produced in 1.4 MeV u ^-1 (0.33 GeV) collisions of U ³²⁺ with Ne. Recoil-ion charge states i=1-8 have been observed; the mean recoil energies are low and do not exceed 1 eV until i>6. Calculations employing a newly developed n-body classical trajectory Monte Carlo method are found to yield results in qualitative agreement with the recoil-ion experiment. Calculations also are presented for the ionisation and charge exchange cross sections, the projectile energy loss and the ejected-electron energy and angular spectra. The importance of fast ejected electrons in the dynamics of energetic multiply charged ion-atom collisions is noted.
