A self-consistent perturbation theory is used to calculate R as a function of D for impenetrable hard walls and soft walls. In both cases, R obeys the predicted scaling behavior in the limit of large and small D. The crossover from the three-dimensional behavior (D→∞) to the fully stretched one-dimensional case (D→0) is nonmonotonic. The minimum value of R is found at D ∼ 0.46RF, where RF is the Flory radius of R at D→∞. The results for soft walls map onto the hard wall case with a larger cylinder radius. date: 2005 date_type: published publication: Journal of Chemical Physics volume: 122 number: 19 publisher: American Institute of Physics pagerange: 194907 id_number: 10.1063/1.1903923 refereed: TRUE issn: 0021-9606 official_url: http://dx.doi.org/10.1063/1.1903923 citation: Morrison, Greg and Thirumalai, D.
