Abstract: This article presents the measurement of Ar metastable 1s_5(3s~23p~54s[3/2]_2) particle number density in He-Ar mixed gas at atmospheric pressure by the emission spectroscopy of the gas radiofrequency capacitive discharge. The important parameters of discharge plasma, gas rotational temperature, electron excitation temperature, and Ar metastable 1s_5 particle number density, are measured at different discharge powers and gas composition. The results show that gas temperature changes little at different discharge power with the content of Ar less than 5*10~3 Pa, and the range is 300-350 K. ...
