摘要：
The superheavy nucleus (294)118 and its alpha-decay chain have been investigated system-atically in the relativistic mean-field (RMF) theory with the interactions NL3, TMA, PK1 and NLZ. The properties of ground state have been described well with the binding energies per nucleon and alpha-decay energies, which are reproduced as compared with the experimental data. It shows that the RMF theory is effective for studying not only the stable nuclei but also the superheavy nuclei presented here. In particular, the prolate shape predicted in the ground state of the sesuperheavy nuclei is in agreement with the experimental data as well as other theoretical calculations.
