    "abstract": "The fine structure of hydrogen energy was calculated by using the usual\nmomentum-wavefunction relation directly, rather than establishing the\nwell-known Dirac wave equation. As the results, the energy levels are\ncompletely the same as that of the Dirac wave equation, while the wavefunction\nis single component that is quite different from Dirac\u0027s four component\nwavefunction, the most important thing is that the present calculation brings\nout electronic spin in a new way which has never been reported and indicates\nthat the electronic spin is a kind of orbital motion.",
