In this note, we revisit modeling the nucleus as a uniformly charged sphere
: in order to examine finite nuclear size effects on atomic binding energie
s. We use nonrelativistic quantum mechanics to extract binding energies of
a negatively charged lepton bound by a uniform-sphere potential. Energies a
re determined by using MATHEMATICA to match interior and exterior solutions
at the nuclear radius. Muonic lead and tin binding energies are found, as
are their fine-structure transition energies, and compared with experimenta
l data. In the course of our reinvestigation of this problem, we came upon
several subtle features of using infinite (especially asymptotic) series fo
r numerical evaluation. Effective handling of these features is made practi
cal both by using certain analytic transformations and the powerful compute
r programs currently available. We believe that these technical observation
s are of value to a wider class of problems beyond the ones considered in d
etail in this paper. (C) 2000 American Association of Physics Teachers.
