摘　　要：应用SHF方法和连续介质模型理论计算结果对超重核^(298)114进行了α衰变寿命、半衰期、基态形状、裂变势垒和壳能级结构研究,并与超重核区其它核素作了比较分析,认为^(298)114最有可能成为超重核中惟一的球形双幻核。Theα-decay life,half-life,the ground state shape,fission barriers and the shell structure for the ^(298)114 nucleus were researched using the theoretical results of SHF approach and continuous medium model,and has made the comparative analysis with other nuclides of superheavy nucleus region,indicated that ^(298)114 is most likely to become the only spherical doubly magic superheavy nucleus.
