I have read from DJ Griffiths Quantum Mechanics that the electron-positron annihilation process will enlarge the hyperfine splitting of the positronium ground state. More precisely, the actual splitting is larger than that we calculated only considering the spin interaction between the positron and the electron in the same way as we did for the hydrogen atom.
Does anyone know how to get an intuitive physical point of view about this? I am a sophomore undergraduate so I can not calculate it using Quantum Electrodynamics now.
Thanks
