Biopolymers Isotropic Scattering of Identical Uncorrelated Particles

6 Biopolymers Isotropic Scattering of Identical Uncorrelated Particles 

Overview. Considerable research activities in the fields of isotropic SAXS and small-angle neutron scattering (SANS) are devoted to the investigation of ensembles of uncorrelated but identical or almost identical complex particles. Frequently these particles are studied in solution. Samples for such investigations must be supplied in a solution in which the particles do not aggregate. 

The majority of the research is focused on colloidal and biological materials. In several textbooks [86,101,136,187] the related methods are elaborated. Recent developments are considered in a review of SVERGUN and Koch [188], 

Classical Analysis. The classical analytical methods are even applicable for 

Finite support of y r), p (r), and g (r) is characteristic for a structure made from uncorrelated particles. Thus the related scattering curve is bandlimited (cf. p. 25). For analysis this property is advantageously utilized.
