Classification of the nickel-like silver spectrum from a fast capillary discharge plasma

Summary form only given. In connection with generating soft X-ray laser emission from silver at 14 nm (4d-4p), spectra of Ni-like AgXX have been observed and analyzed in the 13.7-20.5 nm region. A high-current capillary discharge system has been employed to create highly ionized silver plasma. Forty-three AgXX transitions have been identified with the assistance of calculations performed using the Slater-Condon method with generalized least-squares fits of the energy parameters. The average difference between the measured transition wavelengths and the theoretical values is 0.0026 nm.
