Rather than using Green's function techniques, we tackle the mathematically nontrivial problem of finding exact sum rules for the zeros of Bessel functions $J_ν$, which are extremely helpful when seeking numerical approximations to ground state energies. These results are particularly valuable if $ν$ is neither an integer nor half an odd one.15 pages, LaTeX fileHigh Energy Physics - Theorytext
