Multiple ionization of atoms by energetic, highly-charged ions

Abstract

Recent experimental data and calculations provide insight into the transverse and longitudinal components of the momenta carried away by the receding recoil and projectile ions, and ionized electrons. In particular, the Frankfurt group has made a large number of measurements to provide an understanding of the transverse momentum received by the recoil ion. Recently, Kansas State researchers have been able to observe the longitudinal momentum given to the recoil ion as a function of charge state, and have been able to observe the signature of the electron mass transfer for single and multiple electron capture. The projectile scattering angle is directly related to the transverse momentum transfer, but very few measurements exist for it or the projectile’s longitudinal momentum loss for heavy, multiply charged projectiles. On this topic, work at Oak Ridge has been able to give insight using C6+ + Ne as the prototype system. Ionized electron spectra have attracted considerable interest. Besides the tradition...
