| 摘 要： | 在用双光子激发产生的Xe(5p~56p)原子与N_2分子碰撞过程中,有效地生成了N_2(B~3П_g,v=9～14)振动激发态.观察到相应的Δv=4的N_2(B~3П_g-A~3∑_u~+)辐射跃迁萤光,测量了Xe(6p)原子在N_2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. |
