| 英文摘要 | We calculate the radiative capture cross section for Be-7(alpha, gamma)C-11 and its reaction rate of relevance for the Big Bang nucleosynthesis (BBN). The impact of this reaction on the primordial Li-7 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 C-11 of relevance for the BBN 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. |
