Q-band ESR studies of fossil tooth enamel: Implications for spectrum deconvolution and dating

, : Q-band ESR studies of fossil tooth enamel: Implications for spectrum deconvolution and dating. Radiation Measurements 27(1): 49-58

Q-band ESR spectra of eight samples of powdered fossil tooth enamel from the Florisbad archaeological site in South Africa have been measured. On one of these, spectrum deconvolution of the integrated spectrum has been performed. The results are consistent with a model that describes the ESR signal used in dating studies as a superposition of an axialsymmetrically split signal and two isotropic Gaussian signals. A narrow additional signal with higher radiation sensitivity than the main signal has been observed and this line may affect the dose determination in dating if peak-to-peak amplitudes are used to generate dose response curves.
