Opis:: The autocorrelation functions of positron-electron pairs in InP with indium vacancies in different charge states are calculated in this work. It is found that the autocorrelation function can be used to identify the charge states of vacancies in solids. In the case of perfect lattice the autocorrelation function oscillates on the lattice with the periodicity of the lattice and decays gradually up to about the third layer of the lattice points. In the case of neutral vacancies, the central peak expands significantly, but the nearest peak and dip are greatly reduced. In the case of negative charge states of vacancies, the central peak, however, contracts slightly compared to the case of the perfect lattice, and the nearest peak and dip and the next-nearest peak nearly disappear.

Opis:: Molecular vibrational spectra in 3, 3-dimethyl-1-butanol, $(CH_3)_3$ $CCH_2CH_2OH$, and 3, 3-dimethyl-2-butanol, $(CH_3)_3CCHOHCH_3$, were measured by the inelastic incoherent neutron scattering and mid infrared spectroscopy and for 3, 3-dimethyl-2-butanol additionally by the far infrared absorption method. Experimental results were discussed and compared with the results of the quantum chemical calculations performed by the density functional theory (DFT/B3LYP/6-311G**) and semi-empirical PM3 calculation methods assuming the isolated molecule approximation.

Opis:: Nanostructured materials attract nowadays a broad attention due to their specific properties. Defects play an essential role in material properties so their characterisation is very important. The evolution of the various open volume defects in AgCo nanowire modelled samples obtained using molecular dynamics was studied. Isothermal and isoenergetic deformation mechanisms are considered. General analyses of open volume defects concerning their size and their chemical environment were performed. Positron lifetimes, binding energies, and high momentum parts of the momentum distribution of annihilationγ-quanta were calculated for selected defects.
