充氘钯空心阴极灯中放电气体的质谱研究杨原，王小如（厦门大学化学系，厦门，361005）关键词充氘钯阴极，辉光放电，氦-4质谱钯吸附氢气及氘气的研究已有报道［1］，在一定操作条件下，钯吸附氘后还可能产生异常效应［2］。金属空心阴极灯已被广泛地应用于物理... The behavior of a palladium hollow cathode lamp discharged in deuterium was reported.The lamp was operated at pulse mode with 1μs duration at 110 Hz,900 V and >10 A current.The oscillation of discharge was observed due to the absorption and desorption of deuterium on the palladium surFace layer.The analysis of discharge gas by mass spectrometry showed there was trace amount of helium-4 aFter 30 hours of operation.
