Popis:	The effect of intense laser fields on the resonant electronic-bridge process involving the isomeric E3 transition of $^{235\mathit{m}}\mathrm{U}$, which has a photon energy of 73.5 eV, and an intermediate excitation of an electron from the P1(6${\mathit{s}}_{1/2}$) electronic shell of binding energy 71 eV is investigated for lasers of photon energies 1.16 and 2.32 eV within the intensity range ${10}^{10--}$${10}^{13}$ W/${\mathrm{cm}}^{2}$. It is found that in spite of the hindering effect of power broadening, the ratio \ensuremath{\eta} of the transition probability per unit time in the laser-assisted process to that of the laser-free \ensuremath{\gamma} decay can be enhanced by the intense laser field if the resonance condition is met.
