摘要：

Nanodispersed gold targets (2-100 rim grains) were bombarded for the first time in the nuclear stopping region by 1 MeV Au-5 cluster ions (Sigma(dE/dx)(n) = 45 keV/nm and (E(dE/dX)(c) = 4.5 keV/nm in gold). The total yield of the ejected gold reached high values - Lip to similar to 1.2 x 10(5) at./ion (Au-5) for the grains with sizes comparable with the range of the 200 keV gold ions (similar to 18 nm). The size spectra of gold nanoparticles on the targets were compared with those of ejected gold nanoparticles collected on carbon foils supported by TEM grids. No gold nanoparticles larger than 35 rim appeared in the size spectra of the ejected nanoparticles. (c) 2005 Elsevier B.V. All rights reserved.
