The cross sections for production of hydrogen Rydberg states (n=24-27) in collisions of fast (accelerated to 3.6 keV) hydrogen atoms with H<sub>2</sub>, N<sub>2</sub> and He were measured. Field ionization was used to select states in terms of the principal quantum number n. The field ionizer was calibrated by the ionization of Rydberg states selectively excited by dye lasers. It has been found that the cross sections scale with n in the same way as the cross sections of hydrogen Rydberg state production, when the fast protons exchange their charge on potassium.
