Abstract
Scattering of a scalar particle on a crystalline plane with quadratic cell and identical fixed scatterers is solved precisely. Contradiction of the standard scattering theory is pointed out.
Keywords

[ 8 ]  It is common to write sign + before scattered spherical wave, but it is more appropriate to write there minus, which means redefinition of the sign of the scattering amplitude b. With such a choice positive b corresponds to positive optical potential of a medium u=4πN0b, where N0 is atomic density of the medium [5].
