This paper presents an experimental result on the population of the 23S of Hei in He+Xe gas discharge. The laser-induced fluorescence method was used to find the behavior of the 23S population, and a strong coupling of the 23S with 23P state enabled us to determine the 23S population from the measurement of Hei 5876 A(ring) (23P–33D). The discharge condition considered ranged from 0.2 to 5 Torr in pressure and 20 to 260 mA in discharge current. The measured population of the 23S state in the Xe-mixed condition showed a significant reduction at the pressure of 3 and 5 Torr, but not when the pressure became as low as 0.2 Torr. It was demonstrated that the overall behavior of the observed population was quantitatively explainable with an inclusion of the Penning collision of the 23S with the Xe atom.
