核電荷的屏蔽
英文
screening of nuclear charge-
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-密度點的電子俘獲率的影響,結果表明由於電荷屏蔽的作用其電子豐度變化率須乘以一個0 . 8 0 . 9的因子
