Far-wing excitation and probe approach is employed to investigate the transit-region dynamics of the collisions of Hg (^3P_1) with the rare-gas atoms and the diatomic molecules. The following results are obtained :(1)The absolute absorption coefficients have been determined for the red- and blue-wings of the Hg resonance line at 253.7nm broadened by He, Ne, Ar, N_2, CO,H_2 and D_2. The unduratory satellite structures in the blue wing of the Hg resonance line broadened by Ar are investigated theoretically.(2)The far-wing pump and probe (FEP) technique has been applied to the far-wings of the Hg resonance line broadened by N_2 and CO to srudy the transit-region dynamics of the fine-structure transitions : Hg^<**>(^3P_1)+N_2, CO * Hg^<**>(^3P_0)+N_2, CO.The FEP technique has been also used to study the transit-region dynamics of the chemical reactions : Hg^<**>(^3P_1)+H_2, D_2, HD * HgH,HgD(CHI_2SIGMA^+, v, j)+H,D.Combining the results of (1) and (2), we have determined the probabilities for the transit regions ^^- and ^^- of the collisional quasimolecules to decay to the individual final states of the above collisional processes.As for the Hg^*-H_2 reactive collisiions, the ^^- state is found to be three times more effective in producing HgH than the ^^- state. We have concluded that no "early" barrior is expected on both of the ^^- state and ^^- state surfaces in the entrance channel of the HgH formation.

采用远翼激发和探测方法研究了Hg（^3P_1）与稀有气体原子和双原子分子碰撞的过渡区动力学.（1）测定了253.7nm处Hg共振线被He、Ne、Ar、N_2、CO、H_2和D_2加宽的红翼和蓝翼的绝对吸收系数。从理论上研究了Ar加宽的Hg共振线蓝翼中的起伏伴线结构。（2）用远翼泵浦探测（FEP）技术研究了Hg^**>（^3P_1）+N_2，CO * Hg^**>（^3P_0）+N_2，CO精细结构跃迁的过渡区动力学，并用FEP技术研究了化学反应的过渡区动力学。Hg^**>（^3P_1）+H_2，D_2，HD * HgH，HgD（CHI_2SIGMA^+，v，j）+H，D.结合（1）和（2）的结果，我们确定了碰撞准分子的渡越区^^-和^^-衰变到上述碰撞过程的各个终态的几率.发现在产生HgH方面，^^-态的效率是^^-态的三倍。我们得出结论，在HgH形成的入口通道中，在^^-态和^^-态表面上都没有“早期”势垒。
