... ΔE = μBgB = 0.0021 eV where μB is the Bohr magneton and g is the electron spin g-factor with value very close to 2. This gives an estimate of the internal magnetic field needed to produce the observed splitting: μBgB = (5.79 x 10-5 eV/T)2B = 0.0021 eV B = 18 Tesla This is a very large magnetic field ...
