Abstract

Recently, a review of theoretical methods and data for low-energy electron impact excitation of atomic ions was completed by Pradhan and Gallagher.1 It includes a comprehensive annotated bibliography of articles giving data on this subject. In this chapter we focus on three aspects of a continuing worldwide effort to better understand electron-ion excitation processes for application to astrophysical and laboratory plasma research. The first part is concerned with the evaluation and recommendation of the best of a large body of atomic data available for carbon and oxygen ions. The second is a theoretical effort, called the Iron Project, to calculate collision cross sections and rate coefficients for the electron impact excitation of iron ions. The third is a joint effort to benchmark theory against experiment for the electron impact excitation of selected rare-gas ions.

Keywords
