【 摘 要 】

X-ray emission following charge exchange has been studied at the University of California Lawrence Livermore National Laboratory electron beam ion traps EBIT-I and EBIT-II using a high-resolution microcalorimeter. The measured spectra include the K-shell emission from hydrogenlike and heliumlike C, N, O, and Ne needed for simulations of cometary x-ray emission. A comparison of the spectra produced in the interaction of O8+ with N-2 and CH4 is presented that illustrates the dependence of the observed spectrum on the interaction gas. (c) 2005 Elsevier B.V.
