中文摘要:
      我们发现在负氢化合物存在条件下元素Cs可以发生嬗变转变为Ba.实验证实在室温条件下Cs与负氢发生反应不仅导致Ba同位素浓度的变化,而且会诱导发生Ba同位素比例的变化.这个反应的发生与Ru的催化作用有关.结果表明自然界中Ba的同位素有可能依照我们还未知的Cs与负氢在温和条件下的低能核反应产生.
英文摘要:
      This work reported evidences of Cs to Ba transmutation in the presence of hydride compounds. Experiments identified that the concentration and isotope ratio were changed after reaction of Cs salt with hydride at room temperature. In addition, we confirmed that these phenomena are closely related to Ru catalytic role. Those results imply that some of barium isotope in nature might originate from an unknown low-energy nuclear reaction between Cs and hydride under very mild conditions.
