超重核α衰变寿命的理论研究

Theoretical Studies on α decay Halflives of Superheavy Nuclei

摘要: 建立了计算球形核α衰变寿命的新模型——密度依赖的结团模型(DDCM)。在此基础上，通过引入子核的形变自由度，发展了形变的密度依赖的结团模型，编写了形变的DDCM程序。并系统计算了Z=106—110的超重核α衰变寿命。通过与已有的实验数据的对比分析，发现理论结果和实验数据符合得很好，验证了DDCM在超重核区域的适用性。
We proposed a deformed version of densitydependent cluster model (DDCM) by including nuclear deformation of the daughter nucleus. A systematic calculation of αdecay halflives of superheavy nuclei (Z=106—110) is carried out by the deformed DDCM. The good agreement between theory and data is obtained. It is shown that the deformed DDCM works well in the superheavy mass region.
