Resonant electronic-bridge process of the isomeric transition of 235mU induced by intense laser fields

The effect of intense laser fields on the resonant electronic-bridge process involving the isomeric E3 transition of 235mU, which has a photon energy of 73.5 eV, and an intermediate excitation of an electron from the P1(6s1/2) electronic shell of binding energy 71 eV is investigated for lasers of photon energies 1.16 and 2.32 eV within the intensity range 1010--1013 W/cm2. It is found that in spite of the hindering effect of power broadening, the ratio η of the transition probability per unit time in the laser-assisted process to that of the laser-free γ decay can be enhanced by the intense laser field if the resonance condition is met
