在用55mn和58fe轰击209bi和207pb靶时，用一种灵敏的t1 /2≧1ms自发裂变和重锕系元素α-衰变技术测定了冷聚变反应的产率。结果表明，108号元素的theA= 263 ~ 265同位素（包括偶偶同位素264108）主要发生α-衰变。得到的结果，连同已知的104和106号元素的同位素性质数据，提供了z =108核对自发裂变的增强稳定性的证据。
In bombarding209Bi and207, 208Pb targets by55Mn and58Fe ions the yields of “cold fusion” reactions have been determined using a sensitive technique for detectingT1/2≧1 ms spontaneous fission and theα-decay of heavy actinide elements. It has been shown that theA= 263–265 isotopes of element 108, including the even-even isotope264108, undergo mainlyα-decay. The obtained results, together with the known data on the properties of the isotopes of elements 104 and 106, provide evidence for the enhanced stability of theZ=108 nuclei against spontaneous fission.
