N2(B3Ⅱg)高振动态在Xe原子中的碰撞激发和弛豫
Collisional excitation and relaxation of N2(B3Ⅱg) high vibrational levels in Xe
摘要
在用双光子激发产生的Xe(5p56p)原子与N2分子碰撞过程中,有效地生成了N2(B3Пg,v=9～14)振动激发态.观察到相应的Δv=4的N2(B3Пg-A3∑u+)辐射跃迁萤光,测量了Xe6p原子在N2中的淬灭速率常数,对碰撞弛豫过程进行了讨论.
Abstract
The collisions of two-photon laser excited Xe(5p56p) atoms and nitrogen molecules induce the excitation to N2(B3∏g,v= 9-14) vibrational levels. Subsequent fluorescence emission of N2 (B3∏g - A 3∑u+) with Δv= 4 was observed. The total quenching rate constants of Xe(6p) states in N2 have been measured. The collisionsl relaxation mechanism has been discussed.
