The properties of K isomers are reviewed. Energies and decay hindrance factors are considered in detail for selected isomers in the A≈γβββN≈116 160–190 region, focusing on pairing effects and the key K-mixing mechanisms that influence A≈γβββN≈116-ray decay rates. The A≈γβββN≈116-decay of K isomers is studied, indicating that, far from the valley of A≈γβββN≈116 stability, high-KA≈γβββN≈116-decaying isomers will populate high-K states in the daughter nuclei. The challenges of revealing predicted, but as-yet undiscovered, long-lived isomers in the neutron-rich A≈γβββN≈116 prolate–oblate shape transition region are highlighted, and the occurrence of oblate high-K isomers is discussed. The 2015 multi-quasiparticle K-isomer table of Kondev, Dracoulis, and Kibédi is updated.
