| 摘 要： | We investigate the ground state properties of the new element ^278 113 and of the α-decay chain with different models, where the new element Z=113 has been produced at RIKEN in Japan by cold-fusion reaction Morita et al. J. Phys. Soc. Jpn. 73 (2004) 2593]. The experimental decay energies are reproduced by the deformed relativistic mean-field model, by the Skyrme-Hartree-Fock (SHF) model, and by the macroscopic-microscopic model.Theoretical half-lives also reasonably agree with the data. Calculations further show that prolate deformation is important for the ground states of the nuclei in the α-decay chain of ^278 113. The common points and differences among different models are compared and discussed.
