| Abstract | We used the monochromatic soft-x-ray beamline P04 at the synchrotron-radiation facility PETRA III to resonantly excite the strongest 2𝑝−3𝑑 transitions in neonlike Nixix ions, [2𝑝6]𝐽=0→[(2𝑝5)1/23𝑑3/2]𝐽=1 and [2𝑝6]𝐽=0→[(2𝑝5)3/23𝑑5/2]𝐽=1, respectively dubbed 3𝐶 and 3𝐷, achieving a resolving power of 15 000 and signal-to-background ratio of 30. We obtain their natural linewidths, with an accuracy of better than 10%, as well as the oscillator-strength ratio 𝑓(3𝐶)/𝑓(3𝐷)=2.51(11) from analysis of the resonant fluorescence spectra. These results agree with those of previous experiments, earlier predictions, and our own advanced calculations. | |
