From the observation of the background spectrum in a wavelength range of 200–400 nm, it was found that NO band spectra were enhanced largely with an increase in the addition of O 2  gas. The excitation temperatures ( T  ex ) observed decreased from 5500 to 4800 K with an increase in the percentage of adding O 2  gas from 0 to 20%. The relatively large signal enhancement was observed for all atom lines of Ca, V, Ti, Mg, and Cd when O 2  gas was added to N 2  outer gas. The emission signals for some of ion lines of Ca, V, Ti, and Mg also showed a signal enhancement when a small amount of O 2  gas was added. It was considered that the reason for the enhancement phenomena of the ion lines of these elements was attributed to the mechanism of the charge transfer reaction."}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1381699994115390850","@type":"Researcher","foaf:name":[{"@value":"Masaki
