中文摘要：

本项目的目的是研究重核和超重核性质，主要包括两个方面，一是重核和超重核的衰变和自发裂变性质；二是重核和超重核的结构性质。我们用直接求解薛定谔方程的方法代替半经典WKB近似，建立了计算alpha衰变寿命的纯量子模型—推广的密度依赖的结团模型，并发展该模型以研究形变核alpha衰变和结团放射性。在此基础上，我们进一步完善形变模型，提出了描述形变核衰变到四个子核态的多道结团模型，理论计算表明alpha衰变半衰期和衰变到不同子核态的分支比与实验数据很好地符合。结合最新实验数据，特别是新合成的超重新元素，我们进行了系统的计算和预言，指出超重核的稳定性随着中子数的增加而明显增强。此外，我们还提出了计算重核和超重核结合能和alpha衰变能的新公式，以及描述alpha衰变和结团放射性寿命的统一公式，并研究了重核和超重核alpha衰变和自发裂变之间的竞争机制，以及入射核中子数对熔合反应蒸发截面的影响。在核结构方面，我们用形变相对论平均场模型，引入新提出的FSUGold参数，系统计算了中重原子核基态性质，这对超重核结构的研究有用；我们还在重核区开展了精细结构常数变化和奇A核转动带谱的研究。
