The Schrodinger wavefunction for the hydrogen atom scales as(adsbygoogle = window.adsbygoogle || []).push({}); r^lfor smallr, wherelis the orbital angular momentum. Is this changed in any dramatic way for the Dirac equation wavefuction? Does the small component of the Dirac spinor have the same small-rasymptotic behaviour as the large component? Can someone tell me the smallrbehaviour for the1S j=1/2state and2P j=1/2,3/2states? Thanks in advance.
