Abstract: The paper illustrates the application of CREM (a method for enhancement of spectral resolution) to the EPR spectra of a sample of tooth enamel of a cave bear (J. Nietoperzowa = Bat Cave), mammoth bone (Halicz on the Dniester river) and calcite from cave dripstones (J. Czarna = Black Cave). The application of CREM enabled an accurate determination of positions of EPR spectra lines corresponding to paramagnetic centers. It was proved that the use of CREM enabled a determination of the influence of such physical processes as heating or irradiation, e.g. UV-irradiation, on the dynamics of the paramagnetic centers in a sample studied.
Key words: Electron Paramagnetic Resonance (EPR), Computer Resolution Enhancement Method (CREM), EPR Method of Dating
