Description

Doubly excited or Feshbach-type resonant states in heliumlike systems, Z=2--10, have been calculated using the complex-rotation method. Using Hylleraas-type wave functions having up to 825 terms, we predict resonance parameters (both resonance positions and widths) below the N=3, 4, and 5 thresholds of the hydrogenic systems. The present results for Z=7 and 8 are compared with those of the close-coupling calculations and experimental results where available
