中文摘要：

运用钯元素空心阴极灯和高分辨率光栅单色仪测量了钯原子4d96s和4d95d组态的7个偶宇称能级的发射光谱,确定了这些能级向4d95p组态能级跃迁产生的15条谱线的跃迁分支比.本文大部分结果是对文献中钯元素原子相关光谱参数的重要修正.

英文摘要：

With a hollow cathode lamp and a highly-resolution grating monochromator,the emission spectrum of 7 energy levels from the even-parity configurations 4d96s and 4d95d of palladium （Pd） have been measured. Branching ratios of 15 lines produced by the transitions from these levels to 4d95p levels were derived. The majority of our results can provide corrections for the related atomic parameters of Pd atom in the literature.
