Theoretical electron-impact-ionization cross section for Fe11+ forming Fe12+

We have calculated cross sections for electron impact ionization (EII) of P-like Fe11+ forming Si-like Fe12+. We have used the flexible atomic code (FAC) and a distorted-wave (DW) approximation. Particular attention has been paid to the ionization through the 3l → nl′ and 2l → nl′ excitation autoionization (EA) channels. We compare our results to previously published FAC DW results and recent e...

Theory of Electron Impact Ionization of Atoms

The theory of electron impact ionization of oneand two-electron atoms has advanced significantly in the past two years. This paper will summarize the progress that the members of our research center have contributed to.

Absolute Electron Impact Ionization Cross

Normalized values of cross sections for the production of ions by electron impact on N20 and NO have been obtained by utilizing the relative flow technique. The accurately known values of cross sections for the production of singly charged ions of rare gases from the parent atoms have been used for the normalization. Cross sections for the generation of fragment ions have been measured for the ...
