Caption: Observations made with NIST's Electron Beam Ion Trap indicate that in ions with a strongly positive charge, electrons can behave in ways inconsistent with quantum electrodynamics (QED) theory, which describes electromagnetism. While more experiments are needed, the data could imply that some aspects of QED theory require revision.
Usage Restrictions: None
