超重核^(294)118和^(292)116基态性质的相对论平均场研究

Study on the Ground Properties of Superheavy Nuclei ^(294)118 and ^(292)116 with Relativistic Mean Field Theory

用形变的相对论平均场理论对超重核294118及292116的性质进行了研究.结果表明,这2个核的基态均是超形变的,而且在核294118中可能存在超形变和近球形的形状共存.

With the deformed relativistic mean field theory the properties of the superheavy nuclei ^294 118 and ^292 116 are studied. It is shown that the ground states of the two nuclei are superdeformed. Superdeformation might coexist with nearly spherical deformation in the nuclei ^294 118.
