摘要: 简单回顾了超重核的理论研究现状，讨论了形变对长寿命重核α衰变半衰期的影响。分析了相对论平均场模型的有效范围。强调了α衰变、结团放射性和自发裂变中应保持宇称守恒。提出了一些新观点。
Status of theoretical studies on superheavy nuclei is simply reviewed.We investigate the influence of nuclear deformation on halflives of α decay for
long lifetime nuclei beyond ²⁰⁸Pb. The range of the validity of relativistic meanfield model is analyzed and discussed. The conservation of parity in αdecay, clusterradioactivity, and spontaneous fission of nuclei is stressed. New views on the properties of superheavy nuclei are presented.
