摘要

The X-rays induced during interaction of highly charged argon ions with a beryllium surface are reported. It is found that the K shell X-ray yield of single particle during interaction of hydrogen-like argon ions was 3.6 × 10^-3, which is five orders more than that of helium-like argon ions. Moreover, due to the screening the 2s electron, no K X-ray was emitted during interaction of lithium-like argon ions with the beryllium surface. It is also found that the X-ray spectrum induced by Ar¹⁷⁺ interacting with residual gases is very different from that induced by Ar¹⁷⁺ interacting with the surfaces, that provided an experimental evidence for the existence of the hollow atoms below the surface.
