Note: There may be an error in my simplification of T_4, however the error does not effect the ultra relativistic limit.

$How To Solve The Dirac Equation For The Hydrogen Atom | Relativistic Quantum Mechanics In this video, I show you how to solve the Dirac Equation for the one electron atom. The process used consists of separation of variables, and then a power series treatment of the radial equation. The angular equation is then solved by constructing simultaneous eigenstates of spin and orbital angular momentum. These are called spinor spherical harmonics.

In the second fraction under the square root, the 1s are supposed to be as.
