10. 1u), where the mixing coefficients μ and ν are dependent on the configuration coordinate (Ref. 7).
11. Minima on the potential surfaces exist at configurations slightly lower than tetragonal due to the spin-orbit interaction: for this reason they are named nearly tetragonal (sometimes called rhombic, see Ref. 2, p. 4169). These six minima are labeled X and constitute three couples of nearly degenerate minima.
