通过蒙特卡罗模拟模型检查了 1 mm 厚的辉光放电电池中 1s 3 （帕邢记数法）亚稳态氩原子 (Ar * ) 的速度分布，包括 Ar * (1s 3 )–Ar 弹性碰撞和电池表面 Ar * 原子的碰撞猝灭。为了描述弹性碰撞，根据 Ar * (1s 3 )–Ar 势计算微分截面、碰撞核和碰撞率系数。模型计算出的速度分布与薄池单束吸收光谱测量的Ar * (1s 3 ) 原子的吸收光谱非常吻合。
Velocity distributions of the 1s 3 (Paschen notation) metastable argon atoms (Ar * ) in a 1 mm thick glow discharge cell have been examined by a Monte Carlo simulation model including Ar * (1s 3 )–Ar elastic collisions and collisional quenching of Ar * atoms at the cell surface. In order to describe the elastic collisions, the differential cross sections, the collision kernels and the collision rate coefficients were calculated from Ar * (1s 3 )–Ar potentials. The calculated velocity distributions with the model were in good agreement with the absorption spectra of the Ar * (1s 3 ) atoms measured by single beam absorption spectroscopy with the thin cell.
