The loss of kinetic energy of slow $({v\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}0.3v}_{\mathrm{Bohr}})$ ions transmitted through thin carbon foils has been measured as a function of projectile charge state in the range from $q\phantom{\rule

The emission of secondary electrons and ions from clean Au, CxHyAu and SiO2 surfaces at impact of slow (v ≈ 0.3 vBohr) ions has been measured as a function of incident ion charge for 1 + ≤ q ≤ 75 +. Electron yields from thermal silicon dioxi

Charge states of slow (v{approx}0.3v{sub Bohr}) highly charged ions (O{sup 7+}, Ar{sup 16,18+}, Kr{sup 33+}, Th{sup 65+}) have been determined after transmission through 10nm thick amorphous carbon foils. Up to the highest charge states, ions reach c

We found unambiguous evidence of a new radiation effect from the occurrence of single ion defects which are created through the interaction of the Coulombic potential of slow highly charged ions (e.g. Xe 44+ and U 70+ ) and the surface of solid insul

We present a new technique for selective, highly sensitive, absolute detection of different multiply charged ion species with equal charge‐to‐mass ratios in mixed multicharged ion beams. This is achieved by exploiting the statistics of potential
