Measurement of latent tracks in amorphous SiO2 using small angle X-ray scattering

@article{citeulike:2775928, abstract = {In this paper we present preliminary yet promising results on the measurement of latent ion tracks in amorphous, 2 [mu]m thick SiO2 layers using small angle X-ray scattering (SAXS).
