Angular distributions of the
9Be+
11B elastic and inelastic scattering were measured at
E
lab
(
11
B)=45
 MeV in a large angular range for the transitions to the ground and excited states of the
11B and
9Be nuclei. The data were analyzed within the coupled-reaction-channels (CRC) method. We have also included the data of the
11B+
9Be elastic scattering at
E
cm≈9–22 MeV known from the literature. The mechanisms of the
9Be+
11B anomalous large angle scattering (ALAS) were studied both for the elastic and inelastic channels including the
9Be and
11B reorientations and transfer reactions. The optical potential parameters for the
9Be+
11B elastic scattering and the
11B and
9Be deformation parameters were deduced.
