Beam-gas recoil spectra of highly ionised neon

Abstract

Observations of neon gas recoil spectra from bromine ion bombardment at 81-83 MeV energies are reported. Hydrogenic and helium-like ions were observed with a resolving power of 225. This is improved over previous work with the exception of narrow-range high-precision results of Laming et al. (Phys. Lett. A123 (1987) 395; Phys. Lett. A126 (1988) 253). Current data complementary to these narrow-range results provide wavelengths which show improved agreement with theory compared to earlier work. © 1993.
