摘要：
By means of Mossbauer spectroscopy we have studied the dynamics of nanosized particles when these are dispersed in decalin in the form of a crystalline matrix or as a supercooled liquid. In the case of a crystalline matrix the particles perform Brownian oscillations at temperatures close to the melting point of the decalin. In the case of a supercooled liquid ordinary Brownian motion is observed.
