The basic hydrogen atom is the simplest of all atoms, now known to consist of a single proton and a single electron. Why even physicists still don’t understand quantum theory 100 years on Bohr ...

Two experiment collaborations, the g2p and EG4 collaborations, combined their complementary data on the proton's inner ...

One is the spectroscopy of the internal structure, the internal energy levels of the anti-hydrogen atom to compare them ... "Hydrogen has quantum levels, principal quantum levels (i.e., n=1 ...

For example, the electron in a hydrogen atom attracts the proton that ... "Two-loops" refers to the Feynman diagrams that describe this quantum process—two virtual photons from the quantum ...

The German researcher Walter Gordon had applied the emerging theory of quantum mechanics to the hydrogen atom, the universe’s simplest atom, and worked out exactly how it behaved. A mastery of all ...
