The primordial Big-Bang nucleosynthesis (BBN) model might be more generous in its production of these elements[2]. The radiative-capture cross section for proton capture on 11B leading to 12C is small at astrophysically interesting energies because of the large Coulomb barrier. 关 键 词：FACTORS LOW ENERGIES
