“…Thus only a limited number of transitions can be studied. Recently, we have demonstrated [23,24] an alternative experimental method (use of a of liquid nitrogen cooled hollow cathode discharge lamp with selective optogalvanic and fluorescence laser spectroscopy) to perform similar Zeeman effect studies of the rare earth element atoms (lanthanum and praseodymium), characterized also by very dense spectra. Although this method is Doppler-limited it can give access to a much higher number of levels to be excited.…”

“…We have used a software developed in our group (for details see [15]), which proved its usefulness for many elements, e.g. Antimony [16,17], Lead [18], Bismuth [19][20][21], Lanthanum and Praseodymium [23,24]. In case of the Nd isotopes with hyperfine structure, 143 and 145, in simulations we have used the most recent hyperfine constants reported by [5,6,8].…”

Abstract. The Zeeman splitting at moderate magnetic fields (up to 334 G) of 20 lines of Nd II, covering the part 569.89 nm to 617.05 nm of the visible spectral range were investigated. We used a Doppler-free collinear laser ion beam spectroscopy technique supported by a precise computer analysis. From the Zeeman effect studies we re-investigated the Landé gJ factors for 20 odd levels between 22 850 and 30 002 cm and 11 even levels lying between 6005 and 12 460 cm −1 . We compared our data with other available experimental and theoretical values. We achieved an accuracy better than that of other authors, making our data valuable for future theoretical parametric studies.

For the determination of improved energy levels of ionic spectra of elements with large values of nuclear magnetic dipole moment (and eventually large values of nuclear quadrupole moments), it is necessary to determine the center of gravity of spectral lines from resolved hyperfine structure patterns appearing in highly resolved spectra. This is demonstrated on spectral lines of Ta II, Pr II and La II. Blend situations (different transitions with accidentally nearly the same wave number difference between the combining levels) must also be considered.
