Measurements of H{sup {minus}} stripping and H{sup 0} excited-state production for a wide range of foil thicknesses and experimental conditions are reported. An 800-MeV H{sup {minus}} beam was passed through carbon or aluminum oxide foils of thicknesses ranging from 10 to 550 {mu}g/cm{sup 2} and the excited states produced were analyzed by field stripping in a special magnet downstream of the foil. The foil thicknesses were independently determined. The H{sup 0} atoms emerging in excited states with {ital n}{approx_gt}2 can be stripped to protons in fields of up to 1.3 T. The yield of excited states as a function of foil thickness and the cross sections for the various interactions are presented. The cross-section ratio of double to single ionization of H{sup {minus}} in carbon is found to be (1.8{plus_minus}0.9){percent}. {copyright} {ital 1996 The American Physical Society.}
