Collisions of UFminus;6ions with Ar, Xe, SF6, and UF6

摘要

Electrostatic energy analysis has been performed on the products of collisions of up to 200 eV (lab) UFminus;6ions with Ar, Xe, SF6, and UF6. Negative ions of UF6containing internal excitation energy up to sim;5 eV have been observed and their distributions as functions of scattering angle and internal excitation recorded. The behavior of the fragment ions Fminus;and UFminus;5was investigated and found to be in accord with a simple statistical model of the collision dynamics.
