Revised Landé gJ-factors of some 141Pr II levels using collinear laser ion beam spectroscopy

Research output: Contribution to journalArticleResearchpeer-review

Abstract

Abstract The Zeeman effect of singly ionized praseodymium spectral lines was studied at small magnetic fields up to 334 G, using the high-resolution spectroscopic method of collinear laser-ion-beam spectroscopy (CLIBS), where a collimated fast ion beam is superimposed with a counter propagating laser beam tuned to the desired transition. This nearly Doppler-effect-free technique enables to observe linewidths as low as 100 MHz and thus to record the Zeeman patterns of the hyperfine structure of the investigated spectral lines. From the Zeeman patterns of 21 lines of Pr II lines in the range 570.45–609.038 nm we have re-determined the Landé gJ-factors of 14 levels of the f 3 d odd and 16 levels of the f 3 p and f 2 d 2 even configurations. The obtained experimental Landé factors are compared with available earlier measurements as well as with theoretical calculations.
