Dr. EMANUEL KAMBER, HOMEPAGE

 

 Dr. Kamber's research interests involve experimental atomic collision studies to investigate electron capture (electron transfer between the collision partners), ionization (between removal from the atom or molecule), and excitation (electron jump within he atom or molecule) processes in  ion-atom/molecule collisions.

Recently Dr. Kamber research has centered on the physics of the collisions of low energy atomic and molecular ions with neutral target atoms and molecules by applying the translational energy spectroscopy technique. Processes studied include state-selective dissociative and non-dissociative electron capture and collision-induced dissociation of metastable singly and  doubly charged molecular ions. The experimental method combines translational energy -gain spectroscopy, coincident time-of-flight and position imaging techniques. The translational energy spectroscopy technique involves a precise measurement of the kinetic energies of the collision  products, which leads to more quantitative information regarding the orbitals in which electrons are captured. The research program is centered on the use of 6 MV tandem Van de Graaff accelerator and laboratory facilities including data analysis computer systems. The tandem provides fats ions from pumping a target atom or molecule to a low-energy but highly charged state for the subsequent use as a projectile for low-energy ion -atom/molecule collisions studies. the interest of these processes stem not only from fundamental aspects but also from their importance in the study of the role of impurity ions in controlled thermonuclear fusion and astrophysical plasmas.
