Theoretical scattering curves for monodisperse systems with different volume ratios based on a sphere interference model derived from Eqs. (1) and (2) with K = 1 and R = 1 nm. where K is a constant, R is the radius of the spherically symmetric (or nearly spherically symmetric) particle, V
1 is the average volume offered to each particle, V
0 is the total volume offered to the particles, V
0/V
1 is the well‐defined number of particles contained in V
0, I is scattering intensity, q is the scattering vector, a.u. means arbitrary units.
