Kinetics of multicharged recoil ions produced in swift heavy ion atom collisions

The determination of average recoil energies for Ne 7+ to 9+ and Ar 9+ to 16+ ions produced by 27 MeV/amu Xe 52+ projectile ions are determined. A time-of-flight spectrometer, used for charge state analysis, is sketched. It is shown that the time-of-flight of an ion becomes a linear function of its initial velocity component along the extraction axis. The theoretical time-of-flight peak profiles are calculated for different values of the ratio between velocity at the center, and the half width of the gaussian distribution of the recoil velocities
