在295° K，0.2-100乇的压力范围内，用稳态余辉技术测量了氙-氙混合气体中亚稳态氙~*（3 P ~ 2）浓度的衰减。在1 Torr下，氖中的扩散系数为D′0=143（±10）cm 2 s-1。在两体和三体碰撞中，测量了π *（3 P2）的碰撞猝灭反应速率，对于两体过程π *（3 P2）+Ne，k1=1.85（±0.31）×10−16 cm 3 molecule−1 s−1;对于三体过程π *（3 P2）+ π +Ne，k2=1.19（±0.19）×10−32 cm 6 molecule−1 s−1。XeNe* 准分子的碰撞涉及的？（3 P1）状态也被观察到。
The decay of the concentration of metastable Xe* (3P2) in a neon–xenon mixture has been measured using the stationary afterglow technique in the pressure range 0.2–100 Torr, at 295° K. The diffusion coefficient of Xe* (3P2) in neon has been determined as D′0=143(±10) cm2 s−1 at 1 Torr. The reaction rates for collisional quenching of Xe* (3P2) in two‐body and three‐body collisions have been measured, yielding k1=1.85(±0.31) ×10−16 cm3 molecule−1 s−1 for the two‐body process Xe* (3P2) +Ne and k2=1.19(±0.19) ×10−32 cm6 molecule−1 s−1 for the three‐body process Xe* (3P2)+Xe+Ne. XeNe* excimers resulting from collisions involving Xe(3P1) states are also observed.
