“…Isomers may offer a path to future applications if this rate can be modified and/or controlled. Indeed, the potential to use relatively low-energy electro magnetic interactions, ideally photons from a laser or electrons in a plasma, to stimulate the release of the isomer's energy has attracted considerable attention (see for example [17,[19][20][21][22][23][344][345][346][347]). For illustration, a partial level scheme for 129 Sb is shown in figure 22 (see also section 8.4).…”

Abstract.The structure of nuclear isomeric states is reviewed in the context of their role in contemporary nuclear physics research. Emphasis is given to high-spin isomers in heavy nuclei, with A 150. The possibility to exploit isomers to study some of the most exotic nuclei is a recurring theme. In spherical nuclei, the role of octupole collectivity is discussed in detail, while in deformed nuclei the limitations of the K quantum number are addressed. Isomer targets and isomer beams are considered, along with applications related to energy storage, astrophysics, medicine, and experimental advances.

“…Aside of their nuclear structure interest, isomers can interact with their atomic environment in unusual ways that may open up novel possibilities [148][149][150][151][152][153][154]. It is notable that isomers offer different opportunities compared to nuclear ground states.…”

The suggestion that some atomic nuclei would be able to exist in more than one stable or metastable configuration was proposed by Soddy in 1917. Subsequently, the first experimental example of such an isomeric pair was reported by Hahn in 1921, in the form of two metastable states of 234 Pa, then known as UZ and UX 2 . Nowadays, of the 3437 nuclides listed in the most recent NUBASE evaluation, 1318 have at least one metastable excited state with a half-life of 100 ns or longer. The present work reviews historical aspects of nuclear isomers, and the different physical mechanisms that lead to their formation. Selected frontiers of contemporary isomer research are discussed, with an emphasis on remote regions of the nuclear landscape. Some possibilities for the electromagnetic manipulation of isomers are included.

“…The high-energy-density storage capability of isomers is of long-standing interest [3,21], and ways to release that energy have been sought. The photo-activation of 180m Ta, the sole naturally occurring isomer, has been relatively well studied [22,23], but the need for ≈1 MeV photons to release 75 keV of isomer energy mitigates against practical applications.…”

Abstract. High-K isomers exemplify the coexistence of individual-particle and collective motion in atomic nuclei. Here, the topic is briefly outlined, and some open questions are discussed. These include violations of the K quantum number; the high-spin limit to K isomerism; the fission stability of K isomers; possibilities for manipulation and control of K-isomer decay rates; and access to K isomers in neutron-rich nuclei.
