CREM in application to EPR dating technique

Krzyminiewski Ryszard, Frąckowiak Magdalena

Vol. 5

65--75

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 centres. 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 centres in a sample studied.
