Influence of electron screening potential on electron capture at presupernova stage 電荷屏蔽對(duì)超新星前身星階段電子俘獲的影響
Abstract : the influence of electron screening on electroncaptu re for the most abundant nuclei in massive stars at the presupernova stage is discussed by using the shell model . it is shown that the total rate of chance of el ectronfraction should be multiplied by a factor of about 0 . 8 0 . 9 with the elec tron screeningtaken into account 文摘:利用核的殼層模型,討論了電荷屏蔽對(duì)超新星的前身星階段一些較豐的核在一些重要的溫度-密度點(diǎn)的電子俘獲率的影響,結(jié)果表明由于電荷屏蔽的作用其電子豐度變化率須乘以一個(gè)0 . 8 0 . 9的因子
