【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。更多还原

【Abstract】 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.更多还原
