Recent convergent close-coupling calculations of the ionization cross section of Na by Bray [Phys. Rev. Lett. [bold 73], 1088 (1994)] are in poor agreement with the experimental determinations, most of which were carried out in the 1960s. We report here a measurement of the ratio of the peak ionization cross section to the cross section for excitation of the 3[sup 2][ital P] state near threshold. By normalizing the latter to the theoretical cross section computed by Moores and Norcross [J. Phys. B [bold 5], 1482 (1972)] and more recently by Trail [ital et] [ital al]. [Phys. Rev. A [bold 49], 3620 (1994)], we find an ionization cross section in agreement with Bray within 10%.
