Phys. Rev. A 61, 052716 (2000) [8 pages]Photoionization from excited Mg atomsReceived 7 September 1999; revised 11 January 2000; published 18 April 2000 We present the theoretical results of a comprehensive study of the photoionization from excited Mg atoms in the spectral region below the Mg II 3p2P limit using a B-spline-based configuration interaction approach. The variation of the doubly excited 1,3S, 1,3P, 1,3D, and 1,3F resonance structures along the autoionization series is discussed. The theoretical resonant energy and width, derived from the energy variation of the scattering phase shift across each resonance, are also presented. © 2000 The American Physical Society URL:
