Abstract：
The ground-state properties of superheavy nuclide ²⁹⁴118 and it's α-decay daughters are investigated in the deformed relativistic mean field (RMF) theory with the TMA effective interaction, where the pairing correlations are treated with the usual BCS approximation. Binding energies per nucleon, alpha decay energies and deformations are calculated and compared with the known experimental data. A good agreement between the calculated result and the data is obtained. This shows the validity of RMF theory in studying the ground state properties of super heavy nuclei.
