This paper reports the discovery of a universal 2df404ee6" title="Click to view the MathML source">Z²$Z^2$-dependency of the binding energy of the homonucleus K-shell MIMS (K-MIMS: Metastable Innershell Molecular State bound by K-shell electrons), which has been established by analyzing extensive existing experimental data over several decades. An intuitive analytical theory on the K-MIMS has been developed for the homologous molecules to the $\mathrm{He}_2{}^{⁎}$ excimer, which elucidates the universal Z  -dependent behavior of the K-MIMS. The theory predicts a 1/Z$1/Z$-dependency of the K-MIMS bond length, which is in agreement with the quasimolecule sizes estimated from the x-ray generation cross-sections in H-like Bi⁸²⁺ and U⁹¹⁺ impact on Au solids.
