Transport of Hollow Atoms Through Thin Dielectric Films
PHYSICA SCRIPTA(2001)
摘要
We have determined exit charge states and energy losses of slow, highly charged gold ions after transmission of thin (7 +/- 3 nm) diamond Eke carbon foils. Average charge states of up to 37+ were observed for Th80+ at 8.2 keV/u (0.57 nu (Bohr)). The final charge state is populated through re-arrangement processes after the projectile has left the foil. High final charge states indicate that none of the M-shell vacancies in Th80+ could be filled inside the foil. The increase of the average exit charge state as a function of M-shell vacancies is a sign of strongly enhanced X-ray fluorescent yields for hollow atom decay in vacuum.
