The results of experiments on small-angle neutron scattering from colloidal solutions (dispersions) of fullerene C60 in water are considered, which confirm the high stability of these dispersions and reproducibility of their preparation. The colloidal particles revealed in the solution are characterized by pronounced poly-dispersion. The particles with smooth surfaces have slightly anisotropic shapes and a maximum size exceeding 500 Å. The average scattering density of the particles determined by the method of contrast variation is close to the mean scattering density of fullerene in the crystalline state. The fluctuations of the scattering density inside the particles do not exceed 20 Å. There are some indications that some fullerene molecules in the solution form particles with characteristic size ranging within 10-20 Å.
