In the unknown territory of transfermium nuclei, the relativistic mean-field (RMF) theory has been applied to probe decay modes which include α-decay, spontaneous fission (SF), and a less explored weak-decay. These decay modes are analyzed on equal footing for $101\le \mathrm{Z}\le 109$ and as a consequence, the half-lives for weak-decay are indeed found comparable for several isotopes. Our prediction of decay modes and half-lives are found in excellent agreement with available experimental decay modes and half-lives along with the results of some other theories. Out of α, ${\beta }^{+}$/EC, ${\beta }^{-}$, and SF, the most probable decay mode is anticipated along with its half-life over a wide range of odd and even nuclei to frame a novel sight into terra incognita.

在transfer核的未知领域中，相对论平均场（RMF）理论已被应用于探测衰变模式，包括α衰变，自发裂变（SF）和探索较少的弱衰变。对这些衰减模式进行平等分析$101\le \mathrm{ž}\le 109$结果，确实发现了几种同位素的衰变半衰期可比。我们对衰减模式和半衰期的预测与可用的实验衰减模式和半衰期以及其他一些理论的结果非常吻合。在α中，${\beta }^{+}$/ EC， ${\beta }^{-}$以及SF，最可能的衰变模式及其半衰期在奇数和偶数核的广泛范围内都可以预期，从而构成了一种新的视野。
