The even-even nucleus 270110 was synthesized using the reaction 64Ni + 207Pb. A total of eight -decay chains was measured during an irradiation time of seven days. Decay data were obtained for the ground-state and a high-spin K isomer. The new nuclei 266Hs and 262Sg were identified as daughter products after -decay. Spontaneous fission of 262Sg terminates the decay chain. The measured data are in agreement with calculations using the macroscopic-microscopic model and with self-consistent HFB calculations with Skyrme-Sly4 interaction.
