- The hamiltonian for a system of [tex]N[/tex] non-interacting magnetic moments in a an external magnetic field [tex]\textbf{H}[/tex].

Why product [tex]\textbf{S}_i\cdot\textbf{H}[/tex] may only assume the values [tex]m_iH[/tex] where
[tex]g[/tex] - Lande factor
[tex]\mu_B=\frac{e\hbar}{2mc}[/tex] - Bohr magneton
