论文摘要
PB同位素范围内的衰减模式在176 $ \ leq $ a $ \ leq $ 266中通过使用几种经验公式的半衰期进行了研究。首先对这些公式以及各种理论治疗进行测试，以重现PB同位素的实验性半衰期和已知的衰减模式，因此，这些模式适用于估计的半衰期和未知PB同位素的衰减模式。从稳定到滴水线的同位素之间的$α$ -DECAY和弱量之间进行了比较，这是范围的，这导致了与实验数据和应用经验公式的适用性的极好匹配。此外，将整个PB同位素链被探测为从超重核中的簇排放的潜在候选者，随之而来的是$^{208} $ pb的主要作用，而附近的同位素在可能的簇发射中。
Decay modes in Pb isotopes within the range 176$\leq$A$\leq$266 are investigated by the calculation of half-lives using several empirical formulas. These formulas along with various theoretical treatments are first tested to reproduce experimental half-lives and known decay modes of Pb isotopes, which are in consequence applied to estimate half-lives and decay modes of unknown Pb isotopes. A comparison between $α$-decay and weak-decay from the stable to drip-line isotopes is canvassed which leads to the excellent match with experimental data and applicability of applied empirical formulas. In addition, the full chain of Pb isotopes is probed as potential daughter candidates of cluster emission from superheavy nuclei which ensued the predominant role of $^{208}$Pb and nearby isotopes in probable cluster emission.
