摘要：

We report the first observation of magnetic octupole decay in the x-ray spectrum of a highly charged ion. Detailed analyses of the low-energy region of the n = 3 --> 4 spectra of nickel-like Th62+ and U64+ show an intense line at 2558.7 +/- 0.2 and 2689.3 +/- 0.2 eV, respectively, that is attributed to the transition (3d(9)4s)j = 3 --> (3d10)j = 0. Calculations indicate that the line is almost exclusively excited by indirect processes such as radiative cascades and electron capture.
