Double beam tube
... Fine beam tube or Double beam tube – measurement of e/m for the electron This tube is different from the deflection tube in that it is filled with low pressure helium gas. The advantage of this is that you can see the path of the beam of electrons since they ionise the gas which then glows as the el ...

Chapter 7 - Quantum Numbers, Orbitals, and Electron
... For the H atom the orbital energy depends only on n, so all orbitals with the same value of n have the same energy. This is not true, however, for any other atom! The H atom orbitals may be used to approximate the orbitals for multi-electron atoms. But since these atoms have more than one electron, ...

Quantum electrodynamics
In particle physics, quantum electrodynamics (QED) is the relativistic quantum field theory of electrodynamics. In essence, it describes how light and matter interact and is the first theory where full agreement between quantum mechanics and special relativity is achieved. QED mathematically describes all phenomena involving electrically charged particles interacting by means of exchange of photons and represents the quantum counterpart of classical electromagnetism giving a complete account of matter and light interaction.In technical terms, QED can be described as a perturbation theory of the electromagnetic quantum vacuum. Richard Feynman called it ""the jewel of physics"" for its extremely accurate predictions of quantities like the anomalous magnetic moment of the electron and the Lamb shift of the energy levels of hydrogen.
