Partial autoionisation widths of 2S+1Lo doubly excited O6+ states associated with N = 3 and 4, O7+ threshold

The resonance positions and total and partial widths of somestates of helium-like oxygen ions O6+ 2s+1L° doubly excited autoionizing converging on n = 3 and n = 4 hydrogenic thresholds are reported for L = 1, 2, 3, 4 and 5. The calculation was made in the framework of the diagonalisation method approximation in the LS coupling scheme. The partial widths for multichannel autoionizing levels to sublevels of O7+ were calculated by neglecting the direct coupling between the open channels.
