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.
