The hyperfine structure intervals for the electronic levels belonging to the terms 3 d^5 (^4G) 4s a^5G and a^5P of a chromium 53 atom were precisely measured with the use of the method of atomic beam magnetic resonance detected by laser induced resonance fluorescence. Magnetic-dipole and electric-quadrupole hyperfine interaction constants (A and B, respectively) for the electronic levels of interest were determined with the accuracy of a few kHz. The high precision of measurements also enabled an estimation of the octupole-coupling constants (C).

Biotransformation of L-arabinose to arabitol by selected yeasts was described. P. stipitis CCY 39501, P. guilliermondii DSM 70052, C. shehatae 3504, C. shehatae ATCC 22984, C. pseudotropicalis IPF 65, C. parapsilosis DSM 70125 were investigated to produce L-arabitol. C. parapsilosis DSM 70125 was the best producer of arabitol that was detected in concentrations 10-14 gdm-3 in the medium. The highest yield (0,78 gg-1) and productivity (0,036 g(gxh)-1) were also obtained for this strain. The other quite good producers of arabitol were P. guilliermondii DSM 70052 and C. shehatae ATCC 22984 that produced poliol with yields 0,43 gg-1 and 0,50 gg-1, respectively, in optimal conditions. Rotation conditions of shaker on the level 150 rpm and temperature of incubation 28C were selected to be optimal for biotransformation by all yeasts.

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.
