the dimensional properties of three-dimensional uniform athermal self-avoiding star polymers of small to intermediate molecular weight are determined in the iterative convolution (ic) approximation. the results are compared with continuum monte carlo (mc) simulations and with lattice-based and renormalization group (rg) estimates that relate to the large-n limit. in particular, the present analysis provides direct structural and dimensional assessment of the interior star regimes proposed by m. daoud and j p. cotton, which are inaccessible to the lattice-based and rg treatments. we find no evidence to support the daoud-cotton proposals. on the basis of the iterative convolution approximation, the central core structure of the star terminates at a density discontinuity followed by secondary radial structural features (edited author abstract). 22 refs
