Abstract

Cross sections for the process

H^{+}

+ H →

H^{+}

+ H* (

n = 2

) are determined from the energy-loss spectra of 15-200-keV protons. After normalization at 200 keV to the Born approximation, the maximum value (1.07 ×

10^{- 16}

{cm}^{2}

at 60 keV) lies below close-coupling calculations and above Glauber-approximation calculations. The agreement with low-energy (5-30-keV) data of others is very good.
