Abstract
Excitation of the isomer $^{229m}\mathrm{Th}$ with energy 8.3 eV in the electron bridge (EB) via continuous electron spectrum is treated as a two-step process. At first an outer atomic electron absorbs the laser photon and leaves the atom, afterwards it returns to the atom transferring its energy to the nucleus. This EB transition is described in the framework of strict scattering theory for the atomic-nuclear system with two overlapping resonances. The derived EB cross section differs in some details from the results of P. V. Borisyuk et al. [Phys. Rev. C 100, 044306 (2019)].
