Lifetimes of the 3p 2P1/2, 2P3/2 and 3d 2D3/2, 2D5/2 Levels in Cl VII

Abstract:
The beam-foil excitation technique has been applied to determine lifetimes of the 3p2P1/2, 2P3/2 and 3d2D3/2, 2D5/2 levels in Na-like Cl VII. Using the ANDC method accurate values have been obtained which confirm recent theoretical values and explain some previously noted differences between theoretical and experimental oscillator strengths for transitions in multiply ionized Na-like ions.
