Use rest mass energy of the electron 0.5 MeV Consider an atomic level with quantum numbers n = 2,l = 1 and maximum total angular momentum. a. Find the first order relativistic correction to this level, in electron- %3D volts. b. Find the first order spin-orbit correction to this level, in electron-volts c. Use your result in parts a and b to find the energy of that level.
