First measurements of absolute total cross sections for electron-impact excitation of an intercombination transition to a nonradiating state of an ion are reported. The cross sections for near-threshold excitation of the 4[ital s][sup 2] [sup 1][ital S][r arrow]4[ital s]4[ital p] [sup 3][ital P] transition of Kr[sup 6+] are dominated by dielectronic resonances. The measurements can serve as a benchmark for theoretical predictions of dielectronic resonance structure in the excitation of multicharged ions.
