Summary:The lattice dynamics and the second order elastic constants of scandium are calculated with twelve second order parameters using Keating's approach. The agreement between theory and measurement is satisfactory. The results are compared with those of Wakabayashi et al. who have used the MAS model with seventeen parameters to fit their dispersion data. Auf Grundlage der Methode von Keating und unter Verwendung von Zwolf Parametern Zweiten Grades wurden die Gitterdynamik und die Elastizaetskonstanten von Scandium ausgearbeitet. Die Uebereinstimmung Zwischen Theorie und Experiment ist befriedigend. Die Ergebnisse sind mit denen von Wakabayashi u.a. verglichen, die entsprechend ihnen Dispersions — Angaben das MAS - Modell mit siebzehn parametern benutzt haben.
