“…The FSR value of the marker has been corrected until a least mean difference in the values of intervals has been obtained. The corrected FSR amounts to 149.98 MHz (this value is consistent with the one obtained with a similar method in our earlier works [9,10]). The final values quoted are calibrated with the corrected FSR value of Fig.…”

“…The external active laser frequency stabilization and tuning system, constucted in our laboratory [26], is based, like the original one of Spectra-Physics, on two tunable Fabry-Perot interferometers. The entire stabilization and tuning process is computer-controlled; simultaneously the experimental data are registered; this means that the computer control allows the direct synchronization of the laser frequency tuning and the measurement process.…”

High-resolution Doppler-reduced laser spectroscopic investigations on an atomic beam of 139 La were carried out to study hyperfine structure of 8 odd levels. The magnetic-dipole coupling constants A and the electric-quadrupole coupling constants B were determined and compared with the data from literature, if available.PACS numbers: 35.10.Fk IntroductionThe first works concerning the electronic (fine and hyperfine) strncture of lanthanum atom were conducted already in the twenties and thirties of this century.Meggers [1] in 1932 performed first measurements of a large number of spectral lines of lanthanum atom; on the basis of those measurements Russell and Meggers [2] carried out identification of many electronic levels, mostly belonging to the low-lying configurations; this identification has in most cases been confirmed in later works.The first theoretical works, concerning the even configurations, were conducted by Stein [3]. The assignment of the theoretically determined electronic levels to the measured ones, for the even configurations, was performed by Wilson [4] and Ben Ahmed et al. [5,6], who used the least squares method.Anderson [7] was in 1934 the first to investigate the hyperfine stucture of the isotope 139 of lanthanum atom, using a combination of a spectrograph and a Fabry-Perot interferometer. The continuation of those measurements were the works of Murakawa and Kamei [8], Luhrs [9] and Fischer et al. [10], while Ben Ahmed [11] used Fourier spectroscopy. All of those investigations, performed by means of the classical optical spectroscopy, were of a rather limited accuracy.The first precise measurements of the hyperfine structure of the levels belonging to the ground term were performed by Ting in 1957 [12] with the use of the atomic beam magnetic resonance (ABMR) method. The magnetic-dipole (A), electric-quadupole (B) and magnetic-octupole (C) hyperfine splitting constants were obtained.

“…They also reported hyperfine structure of few lines in neutral Praseodymium [5]. In 1997 A Krzykowski et al studied the hyperfine structure(hf) in the configuration f d s 4 5 6 3 of Pr I and reported the hyperfine constant of the lower level belonging to this configuration y using laser induced florescence LIF technique [6]. In 2001 Furmann et al evaluate three new low-lying levels of Pr II and reported the hyperfine structure of some unclassified lines.…”

Wavefunctions for ground state 4f³ 6s² configuration of praseodymium to calculate energy of fine levels and other spectroscopic quantities

Wave functions for terms with the same orbital angular momentum L and spin angular momentum S, but different parents can be written as a linear combination of the pure parentage wave functions. These wavefunctions are important because various spectroscopic quantities e.g. energy and transition probability can be calculated with the help of these wavefunctions. In this study we present 46 wavefunctions of seventeen terms (
