摘要
The conversion rules under which an algebraic expression can be obtained from a corresponding photoionizationGoldstone diagram have been given systematically in the present work.The electronic correlations in thephotoionization processes then could be studied diagrammatically.The application to atomic scandium shows that thepresent theoretical scheme can give reasonable photoionization cross sections,which agree well with the experimentalresults.
