Schultz distribution, spherical particles

From a range of possible models a Schultz distribution of spherical particles is often found to give the best fits and physically reasonable parameters. This scattering law may be written... 

Pi, p2 are the core/shell SLDs and several particle shapes were used to calculate P(Q). The best fits were given by a spherical core-shell model with a Schultz distribution [3] ofparticle sizes and the aggregation number (i.e. the number of molecules per micelle, Nagg), the shell-SLD (pz) and the breadth parameter in the Schultz distribution (Z) were adjusted to fit the data. Ri and R were calculated from the fitted parameters. 

The I(Q) data were analyzed using the multimodel FISH program [50] a Schultz distribution of spherical particles gave the best fits and most physically reasonable parameters. The scattering law can be written as...
