DAB (Debye‐Anderson‐Brumberger) Model
This model is suitable to analyse the scattering from a randomly distributed, two‐phase system based. The two‐
phase system is characterized by a single length scale, the correlation length, which is a measure of the average
spacing between both regions. The model also assumes an exponential and isotropic decay of the electron‐
density correlation. The scattering density can be written as follows:
Bq
AqI

with A a scaling constant depending from the system, Λ the correlation length and B a background constant.
