Investigation of the Hyperfine Structure of Atomic Niobium (Nb I) Spectral Lines Based on the Lower Energy Levels at 22936, 23010, and 23048 cm-1
2018
Spectral Analysis Review
The hyperfine (hf) structure constants of three atomic niobuim energy levels in the energy range around 23000 cm −1 (at 22936.90, 23010.58, and 23048.58 cm −1 ) are known with only limited accuracy, and the constants of combining levels are sometimes even unknown. Thus we performed laser spectroscopic investigations in the wavelength range between 5600 and 6500 Å, and we excited altogether 16 transitions in which these lower levels are involved. Beside a more precise determination of the hf
