Theoretical transition probabilities have been obtained for 54 n=3 transitions depopulating the 3s3p 1Po, 3p2 3P, 1D, 1S, 3s3d 1D, 3D and 3p3d 3Po, 3Do, 3Fo, 1Fo, 1 Do, 1Po levels, including 14 transitions not yet observed. Some of these predictions have been compared with experimental lifetimes obtained by beam-foil spectroscopy for four n=3 levels of K7+. An excellent agreement is observed between theory and experiment for all the levels.
