摘要：

A spectroscopic analysis of light emitted in the 2000-6000 angstrom wavelength range by Ar7+ and Ar6+ ions produced in Ar8+-He and Ar8+-H-2 collisions at 120 keV is performed. Well resolved fine structure components of 5s-5p and 5p-5d transitions in Ar VIII following single electron capture are precisely measured. Predominant lines due to double electron capture are observed. In particular, strong lines observed both in Ar8+-He and Ar8+-H-2 collisions are attributed to Rydberg transitions 3snl-3sn'l' in Ar VII. Attempts at identifications are made for the transitions 3dnl-3dn'l' (n = 4, 5) with the help of ab initio calculations. Photon emission cross sections for individual lines are determined from the measured data.
