Abstract
The cross-sections and resolving powers of the 11B(p, p') inelastic scattering at Ep = 30.3 MeV are analyzed in the coupled-channels formalism. These calculations suggest a positive value for the quadrupole deformation β2 of 11B (prolate) and give the result β2 = + 0.52.

Résumé
Les sections efficaces et pouvoirs d'analyse de la diffusion inélastique 11B(p, p') à Ep = 30,3 MeV ont été analysés dans le formalisme des équations couplées. Ces calculs suggèrent la valeur positive de la déformation quadrupolaire β2 du 11B (prolate) et donnent le résultat suivant β2 = + 0,52.
