# Hydrogen Cross Section Resonances

## Homework Statement

Why don't hydrogen cross-sections exhibit resonances?

N/A

## The Attempt at a Solution

I was thinking it had something to do with the spin, the fact that is has only one electron, or elastic scattering, but I can't seem to wrap my brain around resonances enough to form any answer that makes real sense. If anyone can lead me in the right direction here that would be awesome- thanks!
