Wavelengths and Energy Levels of the Upper Levels of Singly Ionized Nickel (Ni ii) from 3d 8(3 F)5f to 3d 8(3 F)9s

Wavelengths and Energy Levels of the Upper Levels of Singly Ionized Nickel (Ni ii) from 3d 8(3 F)5f to 3d 8(3 F)9s

Using high-resolution spectra of Ni ii recorded using Fourier transform (FT) spectroscopy of continuous, nickel–helium hollow cathode discharge sources in the region 143–5555 nm (1800–70,000 cm ^−1 , the analysis of 1016 Ni ii lines confirmed and optimized 206 previously reported energy levels of th...
