摘要：
The change of the probability of proton emission in the nuclear photoeffect due to an intense coherent (laser) field is discussed near the threshold, where the hindering effect of the Coulomb field of the remainder nucleus is essential. The ratio of the laser-assisted and laser-free differential cross section is deduced and found to be independent of the polarization state of the gamma field and the two types of initial nuclear state considered. The numerical values of this ratio are given at some characteristic parameters of the intense field.
