Abstract
We performed terahertz time-domain spectroscopy and low-frequency Raman scattering on microwave-treated carboxymethyl starch (CMS-Na), to detect universal boson peak (BP) behavior in glassy materials and fracton which is expected to universally appear in polymer glass. The obtained spectral shape of BP plot a(v)/v2of the CMS-Na-slu, where a(v) is the absorption coefficient, is different from either starch or vitreous glucose of the previous study. It suggests that existence of the fracton in the CMS-Na-slu.
