英文摘要	We report on our recent measurements of relative partial cross-sections sigma(v)(r) in collisions between 56 keV Ar8+ ions and adenine. In collisions of low-energy highly charged ions with a molecular target, long distance electron capture processes are predominant. We present an experiment that allows triple coincidence measurements between charge-analyzed projectiles, electrons and TOF-analyzed recoil ions. From the analysis of the final charge state of the projectile, we obtain the information on the total sigma(s) cross-section of having s electrons captured and stabilized oil the incident ion. The number it of electrons measured in coincidence with the projectile allows LIS to determine the number r of electrons active in the scattering process by the rule r = n + s and consequently to estimate the cross-sections sigma(v)(r) for having r active electrons with s of them stabilized oil the projectile. Correlation studies of fragmented recoil ions are also presented. Depending on the initial parent charge and energy, we observe binary-fragmentation processes (small charges) or multi-fragmentation processes (high charges). (c) 2005 Elsevier B.V.
