On the stability of the nuclei of element 108 with A=263 265
Abstract
In bombarding209Bi and207, 208Pb targets by55Mn and58Fe ions the yields of “cold fusion” reactions have been determined using a sensitive technique for detecting T 1/2≧1 ms spontaneous fission and the α-decay of heavy actinide elements. It has been shown that the A = 263 265 isotopes of element 108, including the even-even isotope264108, undergo mainly α-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 the Z=108 nuclei against spontaneous fission.
