讨论了Z ≥ 100核的同分异构体的作用。最新进展的实验仪器，导致组合在束γ射线和转换电子能谱进行了讨论。本文讨论了Z ≥ 94核的转动谱及其转动惯量。248，250 Fm中给出了导致发现和识别异构体的束内光谱学的例子。在这里，一些注意的是给予分配的核配置从g-因子通过建立在异构体上的耦合带的分支比测量。给出了Z ≥ 82核中最长寿命同分异构体的完整列表。
Abstract The role of isomers for nuclei with Z ≥ 100 is discussed. Recent advances in experimental instrumentation leading to combined in-beam gamma ray and conversion electron spectroscopy are discussed. The rotational spectra of nuclei with Z ≥ 94 and their moments of inertia are discussed. Examples for in-beam spectroscopy leading to the discovery and identification of isomers are given in 248,250Fm. Here some attention is given to the assignment of nuclear configurations from g-factors measured via the branching ratios of coupled bands built on the isomers. A full list of the longest lived isomers in nuclei with Z ≥ 82 is given.
