1. For the ground state 111Cd, μ=-0.5948861(8) nm and I=1/2.
For 245 keV, μ=-0.766(3) nm and I=5/2.
μN=7.622593285(47) MHz/T (per h)
g=μħ/μNI=-0.595*2π/(7.62*1/2)=-0.981 for the ground state.
g=μħ/μNI=-0.766*2π/(7.62*5/2)=-0.253 for 245 keV.
2. μ=gμBS/ħ for the free electron. μB=1/2 in natural units.
g=1ħ/SμB=1/((1/2)*2)=1 -> this disagrees with the results from QED
3. μ=gμNI/ħ=-3.826*7.623*(1/2)/(2π)=-2.321 nm
