Laser interaction with neutrons

We introduce the process of nonresonant; laser interaction with neutrons. A sufficiently strong laser beam can couple with the magnetic dipole of neut rons. The mean force of appropriately arranged laser beams causes specific momentum kicks through the beat of lasers at specific spatio-temporal posit ions. Such a kick corresponds to the neutron interaction with photons in th e extreme low energy regime. We also: suggest a possible method to detect a phase shift of the wave functions of neutrons of energy 3 x 10(-3) eV with and without photon interaction by neutron interferometry, so that an effec tive neutron measurement of the laser kick is realized. The present ultra-s ensitive neutron measurement with lasers introduces anew probe of neutrons in the extreme low energy regime.
