Abstract
The heaviest isotopes of elements to , , , , , , , , , , , and , were identified by means of the Dubna gas-filled recoil separator among the products of the reaction. The details of the observed six decay chains, indicating the production and decay of isotopes and , are presented and discussed. The decay energies and resulting half-lives of these new nuclei show a strong rise of stability with increasing neutron number, validating the concept of the island of enhanced stability for superheavy nuclei [Oganessian et al., Phys. Rev. Lett. 104, 142502 (2010)].
