-Pathways starting from the next most favored configuration, i.e. \cs{} located at position 2, into configuration a and b are investigated, which show activation energies above \unit[2.2]{eV} and \unit[2.5]{eV}.
-The respective barriers and structures are shown in Fig.~\ref{fig:051-xxx}.
-Again, the non-magnetic configuration is obtained.
-If not forced by the CRT algorithm, the structures beyond \perc{50} displacement of the transition into configuration a would likewise settle into configuration b.
+Pathways starting from the next most favored configuration, i.e. \cs{} located at position 2, into configuration $\alpha$ and $\beta$ are investigated, which show activation energies above \unit[2.2]{eV} and \unit[2.5]{eV}.
+The respective barriers and structures are displayed in Fig.~\ref{fig:051-xxx}.
+For the transition into configuration $\beta$, as before, the non-magnetic configuration is obtained.
+If not forced by the CRT algorithm, the structures beyond \perc{50} and below \perc{90} displacement of the transition approaching configuration $\alpha$ would settle into configuration $\beta$.
