Query: The cross sections for inelastic neutron scattering and radiative
  capture in the field of a light wave   The mixing of the levels of a compound nucleus in the field of a
high-intensity light wave is considered. The cross sections for inelastic
neutron scattering and radiative capture are computed with allowance for this
effect. The effect of the electron shell on the effective charge for the dipole
interaction between the neutron + nucleus system and the external
electromagnetic field is taken into consideration.
