Abstract

Neutron captures produce the vast majority of abundances of elements heavier than iron in the Universe. Beyond the classical slow ( s) and rapid ( r) processes, there is observational evidence for neutron-capture processes that operate at neutron densities in between, at different distances from the valley of β stability. Here, we review the main properties of the s process within the general context of neutron-capture processes and the nuclear physics input required to investigate it. We describe massive stars and asymptotic giant branch stars as the s-process astrophysical sites and discuss the related physical uncertainties. We also present current observational evidence for the s process and beyond, which ranges from stellar spectroscopic observations to laboratory analysis of meteorites. Expected final online publication date for the Annual Review of Nuclear and Particle Science, Volume 73 is September 2023.

s过程及其超越

中子捕获产生了宇宙中绝大多数比铁重的元素丰度。除了经典的慢（s）和快（r）过程之外，还有观测证据表明，中子捕获过程在两者之间的中子密度下运行，距离β稳定谷不同。在这里，我们在中子捕获过程的一般背景下回顾了s过程的主要性质以及研究它所需的核物理输入。我们将大质量恒星和渐近巨星分支恒星描述为s过程天体物理站点，并讨论了相关的物理不确定性。我们还提供了s过程及其后的观测证据，从恒星光谱观测到陨石的实验室分析。《核与粒子科学年度评论》第73卷预计最终在线出版日期为2023年9月。请参阅http://www.annualreviews.org/page/journal/pubdates用于修订估算。

期刊介绍： The Annual Review of Nuclear and Particle Science is a publication that has been available since 1952. It focuses on various aspects of nuclear and particle science, including both theoretical and experimental developments. The journal covers topics such as nuclear structure, heavy ion interactions, oscillations observed in solar and atmospheric neutrinos, the physics of heavy quarks, the impact of particle and nuclear physics on astroparticle physics, and recent advancements in accelerator design and instrumentation. One significant recent change in the journal is the conversion of its current volume from gated to open access. This conversion was made possible through Annual Reviews' Subscribe to Open program. As a result, all articles published in the current volume are now freely available to the public under a CC BY license. This change allows for greater accessibility and dissemination of research in the field of nuclear and particle science.
