Beam-foil lifetimes of O VII in the 10–100 ps-range
Measured lifetimes of foil-excited O VII are found to be in good agreement with theoretical predictions. Experimental and evaluational problems are discussed. Examination of the lineλ=20.48 nm shows a blending of the second orderλ=10.24 nm transition in O VIII with 3d−7p,f transitions in O VII.
