Nous introduisons une approche simple et qualitative du type Jahn-Teller pour décrire la reconstruction de la surface (001) du W et nous l'appliquons à l'étude des modes de déformation de haute symétrie. Ceux-ci sont séparés en deux groupes ("in-plane" et "buckled"), le mode du type [MATH]5 étant le plus favorable.A simple qualitative pseudo Jahn-Teller approach to the reconstruction of the W (001) surface is introduced and the results of its application to high-symmetry deformation modes are presented. They are split into in-plane and buckled modes, the [MATH]5 zig-zag mode being most promising
