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.

The first observation of Pr^{+} ions stored in a Paul trap is reported. Initially the ions were observed by the electronic detection method, and further the laser induced fluorescence, following resonance absorption at a certain optical transition in Pr^{+} ion, which is excited from the ground state, was recorded. Moreover, fluorescence signal following the excitation from a low-lying metastable state could be detected. The Paul trap system and some other parts of the experimental setup were constructed within the frame of this work and thus are briefly described in the present contribution.
