V. Frohne et al., MEASUREMENTS OF RECOIL ION LONGITUDINAL MOMENTUM-TRANSFER IN MULTIPLYIONIZING COLLISIONS OF FAST HEAVY-IONS WITH MULTIELECTRON TARGETS, Physical review letters, 71(5), 1993, pp. 696-699
The longitudinal momentum transfer to the recoil ion in collisions of
1 MeV/amu bare F ions with Ne are resolved for final charge states of
both projectile and recoil ions. We observe the recoil to be thrown ba
ckwards in electron-capture events, reflecting the physical impact of
the electron translation factor. The size of the momentum transfer is
in agreement with classical trajectory Monte Carlo calculations for lo
w charge state recoil ions but not for high charge state recoil ions.
