Linear transformation of EPR spectra as a method proposed for improving identification of paramagnetic species in ceramic
چکیده انگلیسی

In the present paper the paramagnetic centres in pottery generated after γ-irradiation were investigated. The computer resolution enhancement method (CREM) was used to increase the electron paramagnetic resonance (EPR) spectra resolution. The measurements were performed at room and liquid nitrogen temperatures. The paper shows the results of non-irradiated and γ-irradiated pottery before and after resolution enhancement. Each EPR spectrum showed a multiple structure after the CREM procedure application. An aluminium hole centre [AlO4]0 has been ascribed to these lines. The g factors are: g1=2.0602, g2=2.0079, and g3=2.0019 and hyperfine splitting is A1=5.5 G and A2≈A3=6.3 G.
