Hafnium is an element. It has an isomer (excited spin state) that was claimed to be easy to decay by x-ray absorption. The measurements were flawed (they refused to test a control sample) and the experimenters and government administrators that gave them money against the advise of reviewers are buffoons.

Nuclear isomers include excited states of nuclei that electromagnetically decay slowly enough for energy storage. However, the emitted gamma rays of the isomer decay come in a burst. Controlled triggering of the isomer decay allows stored energy to be released on demand, and nuclear isomers represent a potential stand-alone energy source. Barriers to developing a practical energy source are triggering and production.
The so-called nuclear isomer materials, which have the theoretical potential for 100 to 1,000 times the energy density of conventional energetic chemical compounds. These materials are of two varieties: shape isomers and spin isomers. In both types, energy is released in the form of gamma rays when the nuclei of the material transition from a higher energy state to a lower. Nuclear isomers, such as Os187, Yt186, Ta180, and Zn66 have been discussed as possibilities. Nuclear isomers, such as hafnium 178m2, store in the nucleus 10,000 times as much energy per gram as TNT.

In theory, isomer high-energy density materials (HEDMs) have potential energy yields orders of magnitude greater than existing chemical energetics. While the development of useful propellants, explosives, or energy sources based on this phenomenon is probably decades away, such extraordinary energy density has the potential to revolutionize all aspects of warfare. Potential applications range from very high-density energetics for propulsion and warheads to high-energy and power density primary sources to address requirements for EM launchers and all-electric propulsion. and its called hafnium

hafinum: a gray, toxic metallic element with a high melting point (over 2000°C), found in most zirconium minerals.
isomer: Chemistry. a compound displaying isomerism with one or more other compounds.
hope that helps u =) plz rate it
