The influence of electromagnetic radiation on nuclear processes is applied to an example of a neutrinoless double electron capture (0ν2ec). For cases with X-ray free-electron lasers (X-ray FELs) and/or inverse Compton X-ray sources, it was shown that such a decay can be significantly enhanced by tuning the system to the resonant conditions through the absorption and/or emission of a photon with the decay resonance defect energy Δ. In this case, the 0v2ec decay rate Γ&sub(2e) of nuclide Z grew linearly with field intensity (S/S&sub(z)) up to the X-ray flux power S&sub(m)~Z*6, while S&sub(z)~Z*6 (Γ/Δ)*2 with decay width Γ of a daughter atom. For the case of &sup(78)Kr → &sup(78)Se − 0ν2eL&sub(1)L&sub(1) capture we find Sz~10*9 W cm&sup(−2) and Sm~10&sup(17) W cm&sup(−2) which indicate a possibility of increasing decay rate to eight orders of magnitude or even larger.
