| 英文摘要 | Be-7 destruction channels are currently a matter of study because of their influence on the Li-7 cosmological abundances. Here, we determine the cross section of the (n, alpha) reaction by using Trojan Horse experimental data for the Li-7(p, alpha)He-4 reaction and correcting for Coulomb effects. The deduced Be-7(n, alpha)He-4 data overlap with the Big Bang nucleosynthesis energies and the deduced reaction rate allows us to evaluate the corresponding cosmological implications. |
