Résumé
Nous avons cherché, par diffusion inélastique de [MATH] et [MATH] à 56 et 65 MeV, des états de symétrie mixte quadrupolaire 2⁺_M du ⁵⁶Fe. Les distributions angulaires de section efficace et pouvoir d'analyse ont été comparées des calculs DWBA macroscopique et microscopique. Nous discutons, tant d'un point de vue théorique qu'expérimentale de la possibilité d'assignation 2⁺_M pour les états 2⁺₂, 2⁺₃ et 2⁺₄ du ⁵⁶Fe.

Abstract
Quadrupole mixed-symmetry 2⁺_M states in ⁵⁶Fe have been searched for by means of inelastic deuteron and polarized proton scattering experiments at 56 MeV and 65 MeV. The measured angular distributions of cross sections and analyzing powers were compared with macroscopic and microscopic DWBA calculations. The 2⁺₂, 2⁺₃ and 2⁺₄ states in ⁵⁶Fe are discussed as the candidates of the 2⁺_M state from experimental and theoretical points of view.
