Nucleosynthesis with Tritium

This paper reports on the possible role of tritium-induced reactions of light nuclei, which may influence nucleosynthesis in short-lived environments such as the third minute of the Big Bang. They may also play a role during the emergence of the neutrino-driven shock front in core collapse supernovae or merging neutron stars at extreme densities. The production of tritium requires a very dynamic and neutronrich environment; under such conditions tritium-induced reactions are expected to play an important role in the development of specific reaction patterns that could lead to a delayed release of neutrons influencing the associated nucleosynthesis. Here, we summarize different possible reaction sequences and discuss the strength and impact of tritium cluster resonances that occur near the tritium threshold in the respective compound systems.

本论文探讨了轻核氚（tritium）诱发反应的潜在作用，这类反应可能会影响诸如大爆炸（Big Bang）后第三分钟这类短时标环境中的核合成（nucleosynthesis）过程。它们同样可能在核心坍缩超新星（core collapse supernovae）的中微子驱动激波前沿（neutrino-driven shock front）形成阶段，或是极端密度下的中子星并合（merging neutron stars）过程中发挥作用。
氚的产生需要极具动态性且富中子的环境；在此类条件下，氚诱发反应有望在特定反应模式的发展过程中扮演关键角色，这类反应模式可引发中子的延迟释放，进而对相关核合成过程产生影响。
本文总结了多种潜在的反应序列，并探讨了在对应复合系统（compound systems）中，氚阈值附近出现的氚团簇共振（tritium cluster resonances）的强度与影响。
