Chapter 3 Magnetism of the Electron

Which produces a magnetic field µ 0I/2r at the centre B so = µ 0 Zev/2!r2 U so = - µ BB so Since r ! a 0/Z, and m evr 㲔 ! U so! -µ 0µ B 2Z4/4!a 0 3 The Z4 variation for inner electrons shows that spin-orbit coupling increases strongly in heavy elements. The formula is wrong by a factor 2 ................
