Collision processes involving highly ionized iron impurities play an important role in magnetically confined fusion plasmas. Available experimental and theoretical cross-section data for electron-impact ionization of ions in the Fe isonuclear sequence in charge states ranging from 1 to 26 are reviewed, and recommended data for each charge state are presented graphically. Contributions to the ionization cross sections due to inner-shell excitation-autoionization have been considered in detail for each ionization stage and make substantial contributions for the intermediate charge states. The role of metastable levels in ionization is also addressed. Maxwellian collisional rate coefficients are calculated from these recommended cross-section data and presented in tabular, graphical, and parametrized form. Comments are made on current research activities leading to future data for Fe ions. 23 refs., 29 figs., 12 tabs.
