- 中文摘要: After further experimental and analytical study, the eighteen lines obtained lastyear have been confirmed as belonging to the 3d-4f diffuse series of the spectrum ofthe singly ionized sodium, Na Ⅱ. Both the observed and the calculated values of thenew 4f levels have been re-determined. By using the same sliding vacuum spark as light source, the known spectrumlines of the singly ionized magnesium, Mg Ⅱ, and of the doubly ionized magnesium,Mg Ⅲ, in the region 6800A-2300A have been observed. There found also about seventyone unknown lines in the above region. Twenty three of these unknown lines havebeen primarily identified and classified as the new lines belonging to the 3d-4p diffuseseries of Mg Ⅲ. The observed values of this new 4p level have been determined.
