Abstract
The effective pairing interaction of intranuclear nucleons near the Fe rmi surface is calculated on the basis of a direct solution to the Bet he-Goldstone equation in the S-1(0) channel for semi-infinite nuclear matter. The resulting effective interaction sharply changes in the sur face region (by an order of magnitude) from a strong attraction near t he nuclear surface to a relatively weak attraction in the bulk of matt er. The hypothesis that pairing in nuclei is superficial is thereby co nfirmed.
