Isotope shift measurements in zirconium by Doppler-free laser polarization spectroscopy

Semiempirical hyperfine structure and ab initio isotope shift predictions in Zr II

“…Moreover, volume shifts (VS) and specific mass shifts (SMS) of numerous configurations of singly ionised zirconium are deduced by means of ab initio estimates combined with a few experimental isotope shift data available in literature: VS 1. Introduction A great deal of experimental work [1][2][3][4][5][6][7][8][9][10][11] was done on the isotope shift (IS) and the hyperfine structure (HFS) of atomic zirconium, but only few HFS and IS measurements have been achieved so far for singly ionized Zr; up to now, 14 optical transitions among the 810 classified by Kiess [12,13] have been studied experimentally. This is due, mainly, like in the case of the other transitionmetal atoms, to the difficulty of obtaining samples of ions in the perturbation-free environment necessary to study free-atom HFS and IS.…”

Zirconium analysis in microscopic spent nuclear fuel samples by resonance ionization mass spectrometry

“…30 Previous studies on the isotopic shift of low energy levels of zirconium proved them to be below 1 GHz. 31,32 This is one order of magnitude smaller than our frequency-doubled laser linewidth of ∼13 GHz. We therefore expect no significant influence of the isotopic shift in the first excitation step.…”
