ABSTRACT
Numerical calculations of partial cross sections for photoionization with excitation and total cross sections for double photoionization of the twoelectron systems https://www.w3.org/1998/Math/MathML"> H e https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9780429076626/6ab3d127-d5ad-4fc2-b942-a98d4a6e8680/content/eq1964.tif" xmlns:xlink="https://www.w3.org/1999/xlink"/> and https://www.w3.org/1998/Math/MathML"> L i + https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9780429076626/6ab3d127-d5ad-4fc2-b942-a98d4a6e8680/content/eq1965.tif" xmlns:xlink="https://www.w3.org/1999/xlink"/> have been performed employing the time-dependent close-coupling method.
