Phys. Rev. A 68, 052708 (2003) [5 pages]Resonance parameters of autoionizing Be 2pnl statesReceived 4 August 2003; published 14 November 2003 We have employed monochromatized synchrotron radiation to measure the Be+ ion yield in the photon energy region of the Be 2pnl(n=3–12) double excitations. The energy positions of the resonances are in good agreement with a previous experiment [J. M. Esteva, G. Mehlman-Balloffet, and J. Romand, J. Quant. Spectrosc. Radiat. Transf. 12, 1291 (1972)] and theoretical calculations. We also report the experimentally determined Fano parameters of the widths Γ and profile parameters q for the 2pns (n<~8) resonances. The q values are about -0.54 except for n=3 with a clearly lower value of -0.93(5). © 2003 The American Physical Society URL:
