The excitation threshold and oscillator strengths for 3p<SUP>6</SUP>3d <SUP>2</SUP>D 3p<SUP>5</SUP>3d4s <SUP>2</SUP>P<SUP>0</SUP>, <SUP>2</SUP>D<SUP>0</SUP>, and <SUP>2</SUP>F<SUP>0</SUP> transitions in Cr VI, Mn VII, and Fe VIII ions of the potassium isoelectronic sequence have been calculated using large configuration interaction wavefunctions for both initial and final states within the LS coupling scheme. Comparison is made with other available results.
