Abstract
We calculated the first‐order perturbation expansion of the mean‐square end‐to‐end distance of polymers in three and four space dimensions. The segments of the chain were assumed to interact via a pair potential with a short‐range repulsive and an additional attractive part. For a purely repulsive potential, the well‐known results of the δ‐function‐pseudopotential approach are recovered, whereas the inclusion of an attractive part leads to a non‐vanishing contribution even for a vanishing binary cluster integral.
