Abstract
We present an experimental investigation of the asymptotic time behaviour of a Brownian system. Our study is based on the properties of the photoncount correlation functions obtained by light scattering from spherical Brownian particles. The statistical analysis of the data is performed by taking into account the effect of the t- 3/2 long time tail. The statistical accuracy reached in the data analysis supports the conclusion that the experimental results are consistent with the existence of a t-3/2 term in the velocity autocorrelation functionKeywords
