SIMULATION OF EXCITED-STATE FORMATION OF HYDROGEN IN TRANSMISSION OF RELATIVISTIC H- IONS THROUGH THIN FOILS

We present a theoretical description of the formation of excited state s H(n) due to the interaction of relativistic H- ions with thin foils. The classical transport theory based on a Monte Carlo-solution of a L angevin equation is generalized to relativistic speeds of the projecti le. Relativistic corrections are introduced to both collision dynamics and kinematics. The n distribution of excited states, H(n), is studie d as a function of the foil thickness and compared with recent experim ental data.
