✦ Synopsis

The Levin u-transform is used as a method of summation of the divergent perturbation series expansion for the conformation factor in the excluded-volume problem of dilute polymer solutions. The rational approximants thereby generated are superior to Pad6 approximants regarding their consistency with other existing theories for the same effect.
