摘要
用染料激光对热管炉中Ba蒸气进行研究时,在4200～4340A波长范围内,发现一宽带结构及一系列Ba原子的非基态能级产生的跃迁线,用Ba_2准分子的解离对可能产生跃迁的动力学过程做了分析,此宽带结构被归结为Ba_2准分子峰.
With the experiments of dye laser shining on Ba generated in a heat pipt oven, we find in the spectrum ranging (from 420.0 to 440. 0nm) a broad-band structure and several Ba lines with transitions not coming from the ground state of Ba. A probable dynamics is given with the hypothesis of the dissociation of Ba dimer. The broad-band structure is ascribed to the absorption peak of Ba dimer.
