Resumen:
Distorted-wave calculations are carried out for the electron-impact
ionization of atomic ions in the Mn isonuclear sequence. Detailed level
to level calculations are performed for the dominant
excitation-autoionization contributions. The validity of the
configuration-average approach is studied and used to calculate direct
ionization and higher n excitation-autoionization, when the level to
level approach proves computationally too demanding. A combination of
the two methods is used to analyze the recent crossed-beams experimental
measurements of Mn5+, Mn6+, Mn7+, and
Mn8+ by Rejoub and Phaneuf [Phys. Rev. A 61, 032706 (2000)].
The comparison between theory and experiment indicates that a large
fraction of the initial population of each measured ion is in metastable
states of excited configurations.
