| 英文摘要 | Theoretical calculations predict (270)Hs (Z=108, N=162) to be a doubly magic deformed nucleus, decaying mainly by alpha-particle emission. In this work, based on a rapid chemical isolation of Hs isotopes produced in the Mg-26+Cm-248 reaction, we observed 15 genetically linked nuclear decay chains. Four chains were attributed to the new nuclide (270)Hs, which decays by alpha-particle emission with Q(alpha)=9.02 +/- 0.03 MeV to (266)Sg which undergoes spontaneous fission with a half-life of 444(-148)(+444) ms. A production cross section of about 3 pb was measured for (270)Hs. Thus, (270)Hs is the first nucleus for which experimental nuclear decay properties have become available for comparison with theoretical predictions of the N=162 shell stability. |
