Abstract：
The stability of super heavy nuclei (SHN) from Z=104 to Z=126 is analyzed systematically, associated with the following theoretical mass tables:FRDM2012[At. Data Nucl. Data Tables 109-110(2016)], WS2010[Phys. Rev. C 82, 044304(2010)], WS-LZ-RBF[J. Phys. G:Nucl. Part. Phys. 42, 095107(2015)] and the updated experimental data AME2016[Chinese Physics C 41, 040002(2017)]. The nucleus with the biggest mean binding energy in each isotopic chain shows systematic regular behavior, indicating that the mean binding energy is a good criterion to classify SHN by their stability. Based on binding energy, the α-decay energy Q_α, two-proton separation energy S_2p, and two-neutron separation energy S_2n are extracted and analyzed. It is found that N=152 and N=162 are sub-magic numbers, N=184 is a neutron magic number, and Z=114 is a proton magic number, which may provide useful information for the synthesis and identification of SHN.
