Electron correlation in the Auger spectra of the Ne+K 2s2p5(3,1P0)3p2S satellites

Calculations incorporating the effects of electron correlation on the Auger energies and widths of the neon 1s 2 (2s2p 5 ) 3,1 P 0 3p 2 S states have given results in agreement with the recent measurements of Pahler et al. The Ne + 1s 2 2s2p 5 1 P 0 3p 2 S autoionizing state is above the Ne 2+ 1s 2 2s2p 5 3 P 0 threshold and, using the theoretical Auger electron energy, its decay width to this channel is computed to be 0.48 eV. At the Hartree-Fock level this quantity is equal to 0.280 eV. The partial width of the 1 P 0 3p 2 S state to the Ne 2+ 2s 2 2p 4 1 D channel is essentially zero while that to the Ne 2+ 2 s 2 2p 4 1 S channel is 0.028 eV.
