摘要

根据理论,团簇放射性成为超重核中一种重要的衰变方式。在这项工作中,我们预测强不对称裂变或团簇发射实际上是目前已知最重的合成同位素$^{294}_{118}$Og$_{176}$的主要裂变通道。我们的理论方法结合了裂变动力学的重要特征,包括量子隧道和随机动力学直到裂变。我们表明,尽管在静态裂变特性(如裂变屏障和自发裂变寿命)方面存在明显差异,$^{294}_{118}$Og$_{176}$中团簇放射性的预测在计算细节方面是稳健的,包括能量密度函数的选择、集体惯性和耗散项的强度。

Cluster radioactivity of Og176118294
According to theory, cluster radioactivity becomes an important decay mode in superheavy nuclei. In this work, we predict that the strongly-asymmetric fission, or cluster emission, is in fact the dominant fission channel for $^{294}_{118}$Og$_{176}$, which is currently the heaviest synthetic isotope known. Our theoretical approach incorporates important features of fission dynamics, including quantum tunneling and stochastic dynamics up to scission. We show that, despite appreciable differences in static fission properties such as fission barriers and spontaneous fission lifetimes, the prediction of cluster radioactivity in $^{294}_{118}$Og$_{176}$ is robust with respect to the details of calculations, including the choice of energy density functional, collective inertia, and the strength of the dissipation term.
