 where $R$ is the radius of the building block, $D_S$ is the **surface** fractal
 dimension, $\xi$ is the cut-off length, $\rho_\text{solvent}$ is the scattering
-length density of the solvent, $\rho_\text{particle}$ is the scattering
-length density of particles and $\phi$ is the volume fraction of the particles.
+length density of the solvent and $\rho_\text{particle}$ is the scattering
