We calculate the radiative capture cross section for 7Be(α,γ)11C and its reaction rate of relevance for the big bang nucleosynthesis. The impact of this reaction on the primordial 7Li abundance is revised including narrow and broad resonances in the pertinent energy region. Our calculations show that it is unlikely that very low energy resonances in 11C of relevance for the big bang nucleosynthesis would emerge within a two-body potential model. Based on our results and a comparison with previous theoretical and experimental analyses, we conclude that the impact of this reaction on the so-called "cosmological lithium puzzle" is completely irrelevant.
