以前在核合成测定中被忽视的 Li-7(H-3,n)Be-9 反应被发现大大增加了大爆炸产生的 Be-9 的预测丰度。对于非均匀密度宇宙,获得的原始 Be-9/H-1 数密度比为 10 到 -13。值得注意的是,最近对 II 星族恒星的 Be-9/H-1 测量结果接近非均匀密度宇宙值。 22 参考文献。
The Li-7(H-3,n)Be-9 reaction, previously neglected in nucleosynthesis determinations, is found to greatly increase the predicted abundance of Be-9 resulting from the big bang. For a nonuniform density universe, a primordial Be-9/H-1 number density ratio of 10 to the -13th is obtained. It is noted that recent Be-9/H-1 measurements in Population II stars approach the nonuniform density universe value. 22 references.
