IV.D204 — Electron quantum numbers

An electron mode on T^2 bound to a nuclear core of charge Z carries four quantum numbers: principal n (total winding depth, breathing operator eigenvalue tier), angular l = 0,...,n-1 (lobe structure on L), magnetic m_l = -l,...,+l (orientation on L), and spin m_s = +/-1/2 (chirality on T^2).
