摘要： 自从1989年Fleischman及Pons[1]发表了用钯阴极电解重水诱导室温核聚变(又叫“冷核聚变”)以来,多数学者对其实验结果持怀疑态度,但研究电解重水过程中氘在钯电极中的行为以及氘和氢性质之间的差异,对了解电化学诱导室温核聚变和氘及氢的贮存与利用都有重要的意义.本文用电化学渗氢技术比较了氘及氢在钯中的吸收和扩散等行为,用正电子湮没技术研究了电解前后钯中电子结构及其缺陷电子结构的变化.

关键词: 氘, 氢, 钯, 正电子寿命, 冷核聚变

Abstract: The absorption, reserve, diffusion of deuterium and hydrogen in palladium, and the positron lifetime of palladium during electrolysis are investigated by hydrogen permeation method and positron annihilation spectroscopy.The results show that the electrochemical behavior of deuterium is almost the same as that of hydrogen, but the amount of deuterium reserved in palladium is lightly less than that of hydrogen and the diffusion coefficient of deuterium is slightly greater than that of hydrogen.The positron lifetime in palladium after electrolysis is increased by 10.5%.The behavior similarity of deuterium and hydrogen and the possibility of "cold nuclear fusion" are disscussed.

Key words: Deuterium, Hydrogen, Palladium, Positron lifetime, Cold nuclear fusion
