Isotope separation in supernova nucleosynthesis and the studies of neutrino oscillation

我们通过从天文学、天体物理学和核物理中引入关于元素成因的跨学科专业知识来研究超新星的核合成。我们发现，倒置中微子质量等级是粒子物理和宇宙学中的基本问题之一，考虑到最近发现的13混合角，它在统计上是首选的。我们还在未测量的中微子-核相互作用截面的量子力学计算、超新星和伽马射线爆发的新模型建立、核宇宙钟的新提出、自1957年以来长期悬而未决的p元素起源的确定等方面取得了一些进展。

We studied the supernova nucleosynthesis by bringing interdisciplinary expertise on element genesis from astronomy, astrophysics and nuclear physics. We found that the inverted neutrino mass hierarchy, which is one of the fundamental questions in particle physics and cosmology, is preferred statistically by taking account of the recent discovery of 13-mixing angle. We also made several progress in quantum mechanical calculations of unmeasured neutrino-nucleus interaction cross sections, new model construction of the supernovae and gamma-ray bursts, new proposal of nuclear cosmic-clock, identification of the origin of the p-elements which was a long-standing unresolved problem since 1957, etc.
