摘要：
The emission spectra in collisions of Feq+ (q = 8-16) with He were measured in the extreme ultraviolet wavelength region at a collision energy of 20 x q keV. The contribution of the double electron capture process cannot be ignored, at least in Feq+ (q = 9-13) collisions. By comparing the emission spectra between charge exchange spectroscopy and an electron beam ion trap (EBIT) experiment, the resonance lines can be distinguished from other emission lines in the charge exchange spectra, and the charge state distribution of trapped ions can be estimated from the observed EBIT spectrum.
