Metastable inner-shell molecular state
![](https://commons.wikimedia.org/wiki/Special:FilePath/MIMS_Illustration_-_Final.jpg?width=300)
Metastable Innershell Molecular State (MIMS) is a class of ultra-high-energy short-lived molecules have the binding energy up to 1,000 times larger and bond length up to 100 times smaller than typical molecules. MIMS is formed by inner-shell electrons that are normally resistant to molecular formation. However, in stellar conditions, the inner-shell electrons become reactive to form molecular structures (MIMS) from combinations of all elements in the periodic table. MIMS upon dissociation can emit x-ray photons with energies up to 100 keV at extremely high conversion efficiencies from compression energy to photon energy. MIMS is predicted to exist and dominate radiation processes in extreme astrophysical environments, such as large planet cores, star interiors, and black hole and neutron star surroundings. There, MIMS is predicted to enable highly energy-efficient transformation of the stellar compression energy into the radiation energy.The right schematic illustration shows the proposed four stages of the K-shell MIMS (K-MIMS) formation and x-ray generation process. Stage I: Individual atoms are subjected to the stellar compression and ready for absorbing the compression energy. Stage II: The outer electron shells fuse together under increasing ""stellar"" pressure. Stage III: At the peak pressure, via pressure ionization K-shell orbits form the K-MIMS, which is vibrationally hot and encapsulated by a Rydberg-like pseudo-L-Shell structure. Stage IV: The K-MIMS cools down by ionizing (""boiling-off"") a number of pseudo-L-shell electrons and subsequent optical decay by emitting an x-ray photon. The dissociated atoms return their original atoms states and are ready for absorbing the compression energy.MIMS also can be readily produced in laboratory and industrial environments, such as hypervelocity particle impact, laser fusion and z-machine. MIMS can be exploited for highly energy-efficient production of high intensity x-ray beams for a wide range of innovative applications, such as photolithography, x-ray lasers, and inertial fusion.
