Abstract: I present recent results of joint work with Holly Carley and Volker Perlick on the Schroedinger spectrum of hydrogen when electron and proton are assumed to be point particles which interact via a Bopp-Land'e-Thomas-Podolsky modification of Coulomb's electrostatic pair energy. (If you've never heard of BLTP, there is a simple way to remember, and if you think it's not important because you've never heard of those fellows, rest assured that Feynman introduced their regularization into QED. QED.) Rigorous upper and lower bounds are presented. Comparison with empirical data place drastic limits on the Bopp parameter of this theory which would seem to spell disaster for it. Oddly enough, general relativity theory seems to tell us that such drastic values are welcome. To sort this out is work in progress, which involves also Shadi Tahvildar-Zadeh, Annegret Burtscher, and Erik Amorim (who can't be with us this Wed.).
