Metastable Innershell Molecular State (MIMS) II: K-shell X-ray satellites in heavy ion impact on solids

Metastable Innershell Molecular State (MIMS), an innershell-bound ultra-high-energy molecule, was previously proposed to explain a ∼40% efficiency of soft-X-ray generation in ∼0.05 keV/amu nanoparticle impact on solids. Here, the MIMS model has been extended and applied to interpreting the experimental K-shell X-ray satellite spectra for more than 40 years in keV-MeV/amu heavy-ion impact on solids. The binding energies of the K-shell MIMS of elements from Al to Ti were determined to be 80–200 eV. The successful extension of the model to the K-shell MIMS confirms that all elements in the periodic table and their combinations are subjected to the MIMS formation.
