Homogeneous polydisperse solute mean form function

2 Homogeneous polydisperse solute mean form function 

Here the monomers have only one contrast length b, but the number of monomers per chain varies (sf — l,. . . ). The intensity (7.3.19) reads 

Let us express the intensity in terms of the form functions HAq) of the molecules with links. By definition [see (7.2.25)] 

In brief, for small values of q, we can express the results in the form 

In the Brownian case, the square radius of gyration is proportional to the molecular mass. Let °A be the proportionality constant
