Studies of Landé g_J-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

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 aprecise computer analysis. From the Zeeman effect studies we re-investigated the Landég_J factors for 20 odd levels between 22 850and 30 002 cm^-1 and11 evenlevels lying between 6005 and 12 460 cm^-1. We compared our data with other availableexperimental and theoretical values. We achieved an accuracy better than that of otherauthors, making our data valuable for future theoretical parametric studies. Graphical abstract: [Figure not available: see fulltext.]
