Comparative Analysis on Theoretical TDCS Hydrogenic 3S-state and DDCS for the Ionization of Hydrogenic 2S-State

Abstract

This paper investigates the differences between double differential cross-sections (DDCS) for the ionization of the hydrogenic 2S metastable state and the calculation of triple differential cross-sections (TDCS) for the ionization of the 3S state hydrogen atoms. We explore the theoretical frameworks used for each and analyze the additional information gained by TDCS measurements. Finally, In order to compare the theoretical hydrogenic 3S and a theoretical setup was created and implemented by electrons in coplanar geometry to compare with 2S state atoms.
