lower energy state, with spin aligned to the external magnetic field, is determined by the Boltzmann distribution. Thus, multiplying the dimensionless g-factor by the nuclear magneton () and the applied magnetic field, and dividing by the Boltzmann constant () and the temperature. Calculating the magnetic moment In the shell model, the magnetic moment of a nucleon of total angular momentum j, orbital angular momentum l and spin s, is given by Projecting with the total angular momentum j gives has contributions both from the orbital angular momentum and the spin, with different coefficients g(l) and g(s): by substituting this back to the formula above and rewriting For a single nucleon .
