Abstract
The structures of the nuclei with the proton number Z=106-110 are systematically investigated using the deformed relativistic mean-field (RMF) theory. The calculated binding energies are in good agreement with experimental ones. The experimental data of α-decay energies are well reproduced by the calculations. Calculations show clearly that a prolate deformation is important for the ground state of these nuclei. The properties of the nuclei on the α-decay chain of 269Mt are predicted.
