    "abstract": "We consider a correction to energy levels in a pionic atom induced by the\nUehling potential, i.e., by a free electron vacuum-polarization loop. The\ncalculation is performed for circular states (l=n-1). The result is obtained in\na closed analytic form as a function of $ Z\\alpha$ and the pion-to-electron\nmass ratio. Certain asymptotics of the result are also presented.",
