    • note
    • A rescaled step size of b′ = 0.926 was found to correct the SCMF radii of gyration so they agree asymptotically with the analytically calculated radius of gyration for Gaussian dendrimers of step size b. The source of this discrepancy is the assumption of a uniform density distribution within each shell which was used in calculating the probability of stepping between shells.

    • note
    • The SCMF model is a more advanced mean field approximation than the Flory theory since it allows radial density variations which affect the quantitative comparison of the excluded volume parameter in the two models, but remarkably do not affect the qualitative behavior.

    • note
    • The SCMF model places the mass of the monomers at the junctions. Thus the mass of the central monomer is included in the mean field density of the central shell which contributes to the radius of gyration. In the Flory theory calculation, the central mass is assumed to be pointlike, and thus it does not contribute to the radius of gyration around the center of the starburst. This accounts for approximately half of the discrepancy between the SCMF and the Flory theory at small generations.
