Figure 2

Symmetry analysis of 30 calculated phonon modes for (Ce,La)Pd2Al2, considering degeneracy. The abbreviation TL signifies the mixed character of longitudinal and transversal polarisation and T signifies a pure transversal character. Each panel highlight modes and branches with selective symmetry, the corresponding labels are above each panel. For details see chapter Results–Phonon dispersion curves in (Ce,La)Pd2Al2.
