Abstract

The initial decay rate of the dynamical scattering factor of a single regular star polymer is investigated with the chain conformational renormalization group method up to first order in e. The reduced relaxation rate is expressed as the ratio of the mobility to the static structure factor, and we have analyzed the two contributions separately. At the Gaussian fixed point we have found a qualitatively different result to that of the standard calculation in three dimensions, and the difference comss from the effect of the ϵ-expansion on the mobility. The renormalization group result at the self-avoiding fixed point describes qualitatively well the behavior of observed in neutron scattering experiments for 12-arm stars in a good solvent.
