The paper presents our recent investigations of the early stage growth of titanium silicides on a modified Si(100) substrate. The substrate was modified by deposition of a minute amount of Ni atoms, and the subsequent flash annealing. This process led to the creation of parallel defect lines on the Si(100) surface. We expected TiSi_2 to form elongated structures on top and/or between the defect lines. Though this idea failed, stable nanostructures were observed and characterized using scanning probe microscopy (scanning tunneling microscopy and atomic force microscopy) methods.

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.
