Abstract
We perform a perturbative analysis of the Aharonov-Bohm problem to one loop in a field-theoretic formulation and show that contact interacti ons are necessary for renormalizability. In general, the classical sca le invariance of this problem is broken quantum mechanically. There ex ists, however, a critical point for which this anomaly disappears. (C) 1994 Academic Press, Inc.
