F. Spinozzi et al., SAS from inhomogeneous particles with more than one domain of scattering density and arbitrary shape, J APPL CRYS, 33(1), 2000, pp. 556-559
The Small Angle Scattering from inhomogeneous particles is very important i
n the investigation of biological systems, where the scattering objects mig
ht be formed by many domains. For these systems, the scattering intensity,
as well as its Fourier transform, are written as a sum of different contrib
utions. In this work, for the simple case of two domains, the form factors
of different scattering particle shapes, such as the oblate, prolate and bi
axial ellipsoids, spherocylinder and disks were calculated by using a Monte
Carlo method. Finally, SAS data of sodium lauryl sulfate micelles in water
were analysed by using a model that accounts for polydispersity and micell
es of different shape.
