Abstract

Production and decay of an isotope 271110 of the 110th element were studied. The isotope was produced by 208Pb + 64Ni → 271110 + n reaction. Fourteen α-decay chains have been assigned to be the decays originating from the isotope 271110. The excitation function of the production cross section was measured. The results have provided a good confirmation of production and decay of the 271110 reported by GSI group. The presence of an isomeric state in 271110 has also been confirmed. Possible isomeric state in 267Hs has also been presented. The production and decay of 272111 has been also investigated in irradiations of 209Bi targets with 64Ni beam. We have observed 14 α-decay chains in total, that can be assigned, on the basis of their time correlations, to subsequent decays from 272111.
