Abstract

The asymmetry of the cross section of the 12C(γ; p0)11B and 12C(γ; p1)11B reactions has been measured in the energy range 40...55MeV using linearly polarized tagged photons of the MAX-lab facility. The asymmetry of the process 12C(γ; p0)11B is Σ ∼ 0:85, that implies one-particle reaction mechanism. The asymmetry of the reaction 12C(γ; p1)11B is smaller, Σ ∼ 0.6...0.7, that may be due to the stronger relative contribution of the 2h − 1p mechanism to the dominant one-particle reaction mechanism.
