Generalized Liquid Drop Model and Its Application

Keywords： heavy nuclei and superheavy nuclei , Generalized Liquid Droplet Model , particle radioactivity , spontaneous fission , fusion reaction

简单介绍了近年来在研究重核和超重核衰变性质及熔合反应方面取得的理论成果和面临的挑战,着重阐述推广的液滴模型(GLDM)理论框架及其应用.基于原子核的质量数、质子数以及反应Q值,GLDM考虑了质量和电荷的不对称性、形状演化、亲近势和温度等,很好地描述了重核和超重核的质子放射性、α衰变、重离子放射性、自发裂变的半衰期和重离子熔合反应截面,同时也研究了原子核的粒子(质子、α、重离子)放射性与自发裂变的竞争.
