Using a technique which is based on dimensional regularization, loop corrections to vertex diagrams of a massless quark moving in a spherical cavity are calculated in an arbitrary covariant gauge. Including the finite one-gluon-exchange diagrams, the corrections to the magnetic moments, vector and axial vector coupling constants, and the various r.m.s. radii of the nucleon are evaluated to order {alpha}{sub {ital S}}. The results are compared with experimental data and previous calculations. Copyright {copyright} 1996 Academic Press, Inc.
