H. Deutsch et al., Calculated cross sections for the multiple ionization of krypton and chromium atoms by electron impact, CONTR PLASM, 41(1), 2001, pp. 73-83
The Deutsch-Mark (DM) formalism has been used to calculate cross sections f
or the single-step formation of Krm+ (m = 2 - 18) and Crm+ (m = 2 - 12) ion
s by electron impact on the neutral atoms. Our calculated cross sections fo
r these multiple ionization processes are compared with available experimen
tal and other theoretical data and systematic trends in the data are highli
ghted.
