EXCIMER FORMATION AND RELUXATION STUDIED BY CROSSED MOLECULAR BEAM EXPERIMENT

用交叉分子束技术研制了测量稀有气体卤素准分子初态分布的实验装置。对Kr^*+F_2KrF体系进行了深入的研究，发现：(1)KrF的高激发态(=50-100)被显著占据，(2)布居分布不是一阶惊讶分布，(3)它更可能是由碰撞的经典动力学模型给出的，(4)从头计算的KrF势能曲线与实验的发射光谱符合得很好。

Experimental apparatus for measuring the initial state distribution of rare-gas halogen excimer has been developed by using crossed molecular beam techniques. The system of Kr^* + F_2 KrF has been thoroughly investigated to reveal that (1) the highly excited vibrational states ( = 50 - 100) of KrF are significantly occupied, (2) the population distribution is not expressed by the first order surprisal distribution, (3) but it is more likely given by classical dynamic model of collisions, and (4) the KrF potential curve of the ab initio calculation gives a reasonable agreement in the emission spectrum with that of current experiment.
