Reducing the size of the large TiO2 particles by a factor of 10
changes the angular distribution of the scattered intensity significantly. There is still preferred forward and backward scattering but now the difference to the other directions is not so large any more:
Filling up the resin with these small TiO2 spheres (1% volume fraction) gives these scattering probabilities:
Note the much larger probability for scattering events compared to the large TiO2 spheres which is the main difference between the two types of TiO2 scatterers discussed here.
