Abstract

In JQSRT 305 (2023) 108596 we have recently published the discovery of two energy levels of the Pr atom that exhibit strong J-mixing. Additionally, we present here the manifold of observed hyperfine (hf) structure patterns. Their appearance of these patterns is not solely determined by the J-values of the combining upper levels; the composition of their wave functions also plays a cruical role. In total, we identified 49 transitions involving the J-mixed levels, and laser-spectroscopic investigations were conducted for 46 of them. Notably, 13 upper energy levels are reported for the first time in this study. We hope that this investigation will serve as a catalyst for semi-empirical or ab-initio calculations aimed at explaining these observations.
