Sg. Karshenboim et al., SOME ANALYTIC RESULTS ON THE UEHLING CORRECTION TO HYPERFINE SPLITTING IN A MUONIC ATOM, Canadian journal of physics (Print), 76(7), 1998, pp. 503-506
We analyze the Uehling correction to the hyperfine structure of the gr
ound state in hydrogenlike electronic and muonic atoms with a pointlik
e nucleus. The results are obtained analytically without any expansion
over Z alpha.
