Abstract:
The collision reaction that Kr(1Sg)+HF(X1Σ+;ν=1,2,3;J=4)→Kr(1Sg)+HF(X1Σ+;ν',J')has been studied using Monte-Carlo trajectory method,and it has been found that Kr atoms have in fluence on the fundamental and overtone vibrational frequency for HF(X1Σ+).The studying results show that,when the initial relative translational energy Et≤251.0kJ/mol,Kr atoms can reduce the particle number reversion of the fundamental vibrational frequency,and increase it of the overtone vibrational frequency,particularly in the energy level ν'=2,and Kr atoms are more strong on relaxing the higher rotational states(J'≥4).Thus,for hydrogen fluoride(HF)overtone frequency laser Kr atoms can obviously increase the strength of light and improve the transmission property in the air.

摘要:
运用Monte-Carlo轨迹法研究了Kr(1Sg)+HF(X1Σ+;ν=1,2,3;J=4)→Kr(1Sg)+HF(X1Σ+,ν',J')的碰撞过程,从而分析Kr原子对HF基频和泛频的影响。研究表明:在初始相对平动能Et≤251.0kJ/mol时,Kr原子能够减少产生基频的粒子数反转,增加产生泛频特别是ν'=2能级的粒子数反转,并且,Kr原子有较强的弛豫高转动态(J'≥4)的能力,因此,Kr原子对HF泛频激光在提高光强和增强大气传输能力方面均有 较大的改善。
