We have measured the cross sections for ionizating one-electron Au{sup 78+} and the total cross sections for electron capture by bare Au{sup 79+} at 10.8 GeV/nucleon in C, Al, Cu, Ag, and Au targets. We made the measurement by magnetically separating the charge states and measuring the fraction of Au{sup 78+} as a function of target thickness for each element. In contrast to the results reported by Westphal and He [Phys. Rev. Lett. {bold 71}, 1160 (1993)], our ionization measurements agree with the calculation of Anholt and Becker [Phys. Rev. A {bold 36}, 4628 (1987)]. Our capture cross-section measurements are in agreement with theory for those targets where radiative electron capture is the dominant capture process. {copyright} {ital 1997} {ital The American Physical Society}
