Original abstract

Diffraction on a crystalline slab formed by point-like scattering centres is treated as a multiple scattering problem based on the Ewald equations. Using general results expressed in a lucid matrix form, the two-beam solution for both coplanar and non-coplanar cases valid near and far from Bragg peaks is found and a detailed comparison of the final formulae obtained with those following from Laues theory is performed.

Czech abstract

Difrakce na kryslalové vrstvě tvořené bodovými rozptylovými centry je řešena jako problém vícenásobného rozptylu založený na Ewaldových rovnicích. Užitím obecných výsledků vyjářených v maticovém formalizmu bylo získáno dvouparskové řešení jak pro koplanární, tak nekoplanární případ.
