We have combined two novel methods, i.e. persistent spectral hole burning and laser assisted growth, to measure the decay time T2 of surface plasmon excitation in metal nanoparticles of different size at constant well defined shape. The measured values of T2 amount to and are independent of size for diameters ranging from 8 to .
