超重核的团簇放射性

Cluster Radioactivity in Super Heavy Nuclei

M. Warda, A. Zdeb, L. M. Robledo

摘要:

簇放射性是在锕系元素中观察到的一种奇异的核衰变,其中轻核被发射出来,而剩余的重质量残留物是双魔$^{208}$ Pb或其附近的核。我们用微观理论研究了重核到Lv $(Z=116)$的这种衰变。结果表明,以$^{208}$ Pb为重碎片的超不对称裂变可能是某些超重核的主要衰变通道。该反应与团簇放射性密切相关。

英文摘要:

Cluster radioactivity is an exotic nuclear decay observed in actinides where a light nucleus is emitted while the remaining heavy mass residue is the doubly magic $^{208}$Pb or a nucleus in its neighborhood. We have investigated this type of decay in heavier nuclei up to Lv $(Z=116)$ within a microscopic theory. It has been found that super asymmetric fission with $^{208}$Pb as heavy fragment may be dominant decay channel in some super heavy nuclei. This reaction is closely related with cluster radioactivity.
