The Kapitza-Dirac effect for atoms in a strong resonant field
Kazantsev A. P. , Surdutovich G.I.
It is shown that the scattering of atoms in a strong resonant field of a standing wave proceeds more effectively than scattering of electrons. A resonant field of power 0.1-102 W is needed to deflect Na atoms through an angle 0.01-0.1 rad.
