| Abstract: | The reflection from a semi-infinite crystal of point scatterers (Fermi pseudopotentials) is calculated exactly. The reflection is given as an infinite product of trigonometric functions. The arguments of these depend on the momenta and Bloch momenta that obey the conservation laws. No further information on the Bloch waves is needed. |
