摘要

Work has proceeded according to schedule on all research topics. Uniquely welldefined clusters of Gold are now available for optical measurements. A comprehensive experimental investigation has been carried out to determine the non-linearity of these samples on a femtosecond timescale. These results are presented below and prove that: the nonlinear refractive index rises and relaxes on a sub-picosecond timescale, the nonlinearity is predominant positive imaginary originating from a hot electron contribution, the nonlinearity is independent of the size of the particle.
