Title: Relativistic effects on giant resonances in electron-impact double ionization

Journal Article · · Phys. Rev. A; (United States)

The electron-impact double-ionization cross section for Fr/sup +/ is calculated in the distorted-wave Born approximation. A giant resonance in the 5d subshell ionization-autoionization contribution to the cross section is found to be quite sensitive to changes in the double-well potential caused by relativistic effects on bound-state wave functions.
