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 Ni 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.
