在微观超不对称裂变模型中研究了极重核的奇异簇衰变。采用具有 FSU Gold 力的相对论平均场模型来获得星团和子核的密度。在双折叠模型中使用具有指数密度依赖性的微观核相互作用DDM3Y1和库仑相互作用来获得簇和子体之间的势。以 WKB 近似计算半衰期值并提取光谱因子。正如之前所观察到的，后面的值被认为与星团的质量具有简单的相关性。对一些可能的衰变进行了预测。
Exotic cluster decay of very heavy nuclei was studied in the microscopic Super-Asymmetric Fission Model. The Relativistic Mean Field model with the force FSU Gold was employed to obtain the densities of the cluster and the daughter nuclei. The microscopic nuclear interaction DDM3Y1, which has an exponential density dependence, and the Coulomb interaction were used in the double folding model to obtain the potential between the cluster and the daughter. Half-life values were calculated in the WKB approximation and the spectroscopic factors were extracted. The latter values are seen to have a simple dependence of the mass of the cluster as has been observed earlier. Predictions were made for some possible decays.
