Introduction In Sec. 46.9 we carried out a nonrelativistic approximation to the Dirac equation through order (v/c)2, relative to the rest-mass energy mc2, obtaining the Pauli equation including the µ·Bterm with g= 2. In these notes we will carry out the expansion through order (v/c)4. To do this we will
