【 摘 要 】

The 2p6autoionization cross section of Na atoms was measured over the incident electron energy range from the lowest autoionization threshold at 30.77 eV to 37.2 eV. The observed structure was assigned to the negative-ion resonances based upon the lowest autoionizing configurations 2p53s2and 2p53s3p.
