摘要
我们使用最先进的Python软件包PRyMordial计算了在中子寿命τ n = 840 - 1050s范围内氦-4和氘的大爆炸核合成丰度。我们展示了两种不同的核反应速率的结果，由NACRE II和PRIMAT合作计算。
Neutron Lifetime Anomaly and Big Bang Nucleosynthesis
We calculate the Big Bang nucleosynthesis abundances for helium-4 and deuterium for a range of neutron lifetimes, τ n = 840–1050 s, using the state-of-the-art Python package PRyMordial. We show the results for two different nuclear reaction rates, calculated by NACRE II and the PRIMAT collaborations.
