摘要

如果知道产生这些同位素的核反应速率，那么在陨石前太阳晶粒中测量到的硅同位素比率就能提供有关这些同位素的核合成起源的有用信息。决定硅同位素丰度的关键反应之一是（(^{29}\)Si(p,\(γ\))（(^{30}\)P）。在本研究中，利用活化技术高精度地测量了 \(E_textrm{p}\) = 416.9 keV共振的强度。新的（(\omega \gamma = 219 \pm \) 16 meV的强度可以用于更新的反应速率估计和天体物理模型。

Measurement of the \(E_\textrm{p}=416.9\) keV resonance strength in the \(^{29}\)Si(p,\(\gamma \))\(^{30}\)P reaction

Silicon isotopic ratios measured in meteoritic presolar grains can provide useful information about the nucleosynthesis origin of these isotopes if the rates of nuclear reactions responsible for their production are known. One of the key reactions determining the Si isotopic abundances is \(^{29}\)Si(p,\(\gamma \))\(^{30}\)P. Its reaction rate is not known with sufficient precision due in part to some ambiguous resonance strength values. In the present work, the strength of the \(E_\textrm{p}\) = 416.9 keV resonance has been measured with high precision using the activation technique. The new strength of \(\omega \gamma = 219 \pm \) 16 meV can be used in updated reaction rate estimations and astrophysical models.
