| Abstract: | Data on dynamic light scattering from cluster solutions of C60 fullerenes in N-methylpyrrolidone (NMP) and its mixture with water are analyzed. Initial C60/NMP solutions kept for two weeks (i.e., fresher than those analyzed previously) are considered, where the effect of cluster-state reorganization after adding water is recorded more reliably. Based on the size-distribution functions of the clusters, obtained from dynamic light scattering data, model curves of small-angle neutron scattering are calculated and compared with the experimental data. |
