Dose determination on fossil tooth enamel using ESR spectrum deconvolution with Gaussian and Lorentzian peak shapes

Abstract

ESR spectrum decomposition was carried out with the commercial PeakFit program using Gaussian and Lorentzian peak shapes. The results show that there is at least one component in the ESR spectrum that yields significantly lower dose values than the central peak region which is used for conventional peak-to-peak dose determinations. Both deconvolution methods yield closely similar results to simple plateaux dose assessments, which are presently much faster to perform.
