EUV emission spectra in collisions of multiply charged Sn ions with He and Xe

Abstract

Extreme ultraviolet emission spectra of multiply charged Sn ions were measured in the wavelength range 5–38 nm, following electron capture into the excited states of slow Snq + (q = 5–21) ions passing through He and Xe gas targets. Identification of the transitions was carried out by comparison with calculations using the Hebrew University Livermore Laboratory Atomic physics Code. The target and the charge-state dependences of 4d–nℓ (nℓ = 4f, 5p and 5f) and 4p–4d transitions were observed.
