Optical Phonon Anomaly in CeBe sub 13 and Ce sub 1--x La sub x Be sub 13
The two (q approx = 0) breathing ( Gamma exp + sub 1 ) modes of CeBe sub 13 show a softening with respect to the stable valence compounds. This softening increases upon Ce dilution in Ce sub 1--x La sub x Be sub 13 . The latter shows for 0 < x < 1.0 a softening in all other symmetry modes whic...

| Zusammenfassung: | The two (q approx = 0) breathing ( Gamma exp + sub 1 ) modes of CeBe sub 13 show a softening with respect to the stable valence compounds. This softening increases upon Ce dilution in Ce sub 1--x La sub x Be sub 13 . The latter shows for 0 < x < 1.0 a softening in all other symmetry modes which parallels the variation of the Debye temp. 11 ref.--AA |
