In bombardments of 248Cm with 143.7–146.8 MeV 26Mg ions the nuclides 269Hs and presumably 270Hs were produced. After chemical isolation, Hs atoms were identified by observing genetically linked nuclear-decay chains. Three chains originating from 269Hs confirmed the decay properties observed previously in the decay of 277112. Two chains exhibited the characteristics expected for the new nuclide 270Hs, which was predicted to be a deformed ‘doubly magic’ nucleus. From the measured Eα = 9.16+0.07-0.03 MeV an α-decay half-life of 3.6+0.8-1.4 s was estimated. [ABSTRACT FROM AUTHOR] |
