直接反应核天体物理学

Nuclear astrophysics from direct reactions

C. A. Bertulani

摘要:

精确的核反应速率是恒星原初核合成和流体静力燃烧所必需的。在小天体物理能量下,在实验室中直接测量相关的反应是极其困难的。近年来,直接反应已经发展并应用于提取低能天体物理S因子。这些方法需要结合新的实验技术和理论的努力,这是本演示文稿的主题。

英文摘要:

Accurate nuclear reaction rates are needed for primordial nucleosynthesis and hydrostatic burning in stars. The relevant reactions are extremely difficult to measure directly in the laboratory at the small astrophysical energies. In recent years direct reactions have been developed and applied to extract low-energy astrophysical S-factors. These methods require a combination of new experimental techniques and theoretical efforts, which are the subject of this presentation.
