The zero temperature spectrum of excitations (and Fermi energy of the kinks for $zH>M_0$, respectively) $\epsilon_j(0)$ obtained from the numerical solution of (3.4) as function of the magnetic field for $N_f=3$. The number and masses of the breather modes depend on the value of $\nu$. In this plot $\nu = 3$. The low lying modes with energies described by the auxiliary functions are clearly separated from the spectrum of kinks, antikinks and breathers. Their degeneracy is lifted as soon as the kink gap closes.
