Abstract：
RIKEN has produced the new element Z=113 by cold-fusion reaction. Here we systematically study the new nuclide ²⁷⁸113 and its α-Decay chain using deformed relativistic mean-field theory with three sets of force parameters,TMA,NL-Z2 and NL3.The results are compared with those of the Skyrme-Hartree-Fock model, Moller et al and also with the new experimental data. The experimental decay energies are well reproduced with RMF.This not only shows the alidity of self-consistent field theoretical model in researching the ground state properties of superheavy nuclei, but also shows that prolate deformation is important for the ground state of these nuclei.
