Abstract:
Laser-stimulated enhancement of p-wave radiative capture of low energy neutron is studied, with aiming at investigations of p-wave neutron resonance near neutron binding energy, which can not be observed in the usual low energy neutron induced reactions. The cross sections for such processes are calculated in second order perturbation theory and expressed in term of the intensity of laser radiation and the nuclear matrix elements. Numerical estimates show that an appreciable enhancement of the radiative capture will not be observed until the laser electric field strength reaches a magnitude of 105 to 108 (V/cm), depending whether an s-wave resonance exists simultaneously in the entrance channel.
