Investigation of the hyperfine structure of¹⁴³Nd⁺spectral lines using collinear laser ion beam spectroscopy

Abstract

The high resolution technique of collinear laser ion beam spectroscopy is used to determine the hyperfine structure constants of 6 metastable even-parity levels (E < 10 000 cm−1) and 19 odd-parity levels (E < 27 000 cm−1) of 143Nd+. The magnetic dipole interaction constants A and the electric quadrupole interaction constants B were determined with high accuracy. For six levels the hyperfine interaction constants were measured for the first time.

Investigations of the Zeeman effect of some 142Nd ionic levels, using collinear laser ion beam spectroscopy

“…In the fitting procedure for 143 and 145 isotopes we have used the set of hyperfine constants from ref. [19]. The spectrum of the 142 isotope (I=0, no hyperfine structure) has a much smaller number of components, leading to a better signal to noise ratio.…”

Studies of Landé gJ-factors of singly ionized neodymium isotopes (142, 143 and 145) at relatively small magnetic fields up to 334 G by collinear laser ion beam spectroscopy

“…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].…”

“…The isotope shifts and hyperfine structure constants of many Nd II levels were investigated many times in the past, also recently using high resolution Doppler free spectroscopy, e.g. [4][5][6][7][8].…”
