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

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

“…Because a single level can be involved in several transitions, for two odd and six even levels Landé factors were measured at other transitions in our previous paper [9]. Although we have increased the sensitivity and studied systematically weaker Nd II transitions than in previous studies, we did not avoid the repetition of the measurements in case of such levels.…”

“…Like in previous papers [9,10], the measurements were performed on the CLIBS apparatus named after its original localization, MARburg Separator MARS-II, first installed at the University of Marburg a.d. Lahn (Germany) and moved 2002 to Graz (Austria).…”

“…Details of the apparatus were given in [9][10][11]. A continuous-wave narrow band tunable ring-dye laser (with line width ca.…”

“…Compared to our previous experiment [9,10] we introduced several modifications (given in details in [12]), mainly connected with the improvement of parameters of the ion beam. In this way, we have increased significantly the signal-to-noise ratio (S/N) and the density of the ions in the beam.…”

“…Thus Doppler-effect-free methods seem to be more adequate. In our previous studies [9] we already have used a Doppler free method to study the Zeeman effect of Nd II lines. Since that time we have modified some details of the experiment in order to increase the signal to noise ratio and to observe weaker Nd II transitions in the wavelength region of our laser system and to study other levels.…”
