Abstract:The photoionization of the ground state of neon-like ions is investigated, and the autoionizing spectrum of 2s22p5 (2P1/2)ns,nd and 2s2p6 (2S1/2)np Rydberg series of Al IV is studied by using the Breit-Pauli Hamiltonian within the R-matrix theory combining with the QB method of Quigly-Berrington (Quigley L, Berrington K A, Pelan J. Comput Phys Commun 1998;144:225). We predict the autoionizing energy levels and widths of four Rydberg series of Al IV.
Keywords:Photoionization  R-matrix  QB method
