Classical quantum simulation suggests the formation of Ag-3(2+) [Chem. Phys. Lett. 389 (2004) 150]. We present the effect of water pool radii on the transient absorption spectra of initial silver clusters. Experimental evidence for the formation of Ag-3(2+) in micro-emulsion system is reported for the first time. The surface plasmon absorption band of stable silver clusters obtained by bombardment of electron pulses in water-in-oil microemulsions showed absorption maximum at 405 nm. The transmission electron micrograph studies showed the presence of silver nanoparticles having an average size of 10 nm. (C) 2004 Elsevier B.V. All rights reserved.
