Scientific 1986 PHD under supervision of Michel Barat on the electron capture mechanisms from highly charged ions in gas phase. Work sponsored by Fusion science to limit the power loss due to radiative emission from high Z contaminant inside magnetic fusion plasma. Development of first 2D position sensitive detectors. First used in the focal plane of electrostatic analyzer to record simultaneously scattering angle and energy loss. First coincidence measurements between recoil ions and scattered projectile. Identification of reaction path; are the electrons capture one by one or altogether? Identification of driving mechanism; what is the importance of electron correlation? *Differential cross sections for one and two electron capture by highly charged ions.* Roncin-P, Barat-M, Laurent-H. Europhys. Lett. **2** p371. (1986) 1987 Post-doc at NIST Washington DC, Surface Science Division. Investigation of electron emission from surface under ion impact; identification of binary collisions contributions. 1987-1993 Hired at CNRS, I developed projects related with Highly Charged Ions. -Observation of orientation propensities via the circular polarization of emitted light. First triple coincidence between emitted light, recoil ion and scattered projectile. Simple Quasi-molecular model (coll. V.N. Ostrovski, N.O. Andersen and M. Barat). *Observation of orientation propensity for electron-capture in multiply charged ion atom collisions*. Roncin-P. *et al.* Phys. Rev. Lett. 65 p3261 (1990). -Multiple electron capture from many electron atomic targets such as Ar and Xe. Can we build a simple model for such a complex situation where more than ten electrons are active? *Multiple electron capture by highly charged ions at keV energies.* Barat-M and Roncin-P. J.Phys.B. **25, p**2205-2243 (1992). -Investigation of the competition between radiative and Autoionisation decay. Given the fact that two electrons are captured in highly excited states, how likely is it for the projectile to keep them? -Observations of stabilization ratios orders of magnitude larger than predictions. Identification of the importance of excited Rydberg series straddling the doubly excited states during the post-collision. Derivation of a model of “autotransfer to Rydberg states” pointing the crucial role of the increase of angular momentum to bypass di-electronic interaction (Coll. A.K. Kazanski, H. Bachau). *Stabilization of autoionizing states during ion-atom collisions*. Bachau-H, Roncin-P and Harel-C.

First coincidence between emitted electrons scattered projectile analyzed in charge state energy loss and scattering angle. Quantitative measure of the importance of the re-scattering of electrons emitted above the surface. *Interaction of slow multicharged ions with solid surfaces*. Arnau-A *et al.* Surf. Science Reports. **27**, p 117-239 ( 1997) -Identification of the population of electronically excited states on the surface. (energy losss without electron emissions). Derivation of a model involving transient negative ions. It explains why ionic insulators emit more secondary electrons than metals, in spite of a lower work function. *Energy loss of low energy protons on LiF(100): Surface excitation and H- mediated electron emission.* Roncin P *et al.* Phys. Rev.
