Mean energy losses of 10.4-MeV neutral hydrogen atoms penetrated through thin carbon foils of 3.7{endash}13.4 {mu}g/cm{sup 2} were measured using a high-resolution magnetic spectrograph. The measured particles are those entered into the carbon foil as H{sup 0} and emerged from it as H{sup 0}. From the attenuation measurement of H{sup 0} in the foils, we can regard the energy losses as those of H{sup 0} in a frozen charge state. The measured stopping power of carbon for 10.4-MeV H{sup 0} is 21.3{plus_minus}1.8 eV/({mu}g/cm{sup 2}) and is about one-half that for H{sup +} at the same speed. This result agrees well with the theoretical predictions based on the first-order Born approximation. {copyright} {ital 1996 The American Physical Society.}
