电荷屏蔽对超新星前身星阶段电子俘获的影响

Influence of Electron Screening Potential on Electron Capture at Presupernova Stage

利用Langanke等人给出的新的弱相互作用理论,分析了在超新星前身星阶段,电荷屏蔽对电子俘获的影响.分析中屏蔽势采用最近Itoh等人用线性响应理论导出的结果.表明在高密情况下电荷屏蔽对电子俘获率的影响是明显的.

Using the new weak interaction conclusion given by Langanke et al., we have analysed the influence of electron screening potential on electron capture at the presupernova stage. During the analysis, we have used screening potential given by Itoh et al. derived by linear response theory. The result indicates that, in high density, the influence of electron screening on electron capture is obvious.
