Abstract: | The problem of Borrmann absorption (anomalous absorption) of X-rays in weakly deformed crystals is considered on the basis
of Takagi’s approach to the dynamical theory. Using wave function considerations, the attenuation of rays is represented by
exp(−σl) where the attenuation factor σ includes a parameter of the lattice deformation field. The possibility of cases σ = 0 and
even σ < 0 is discussed. |
