The structural features of penta-twinned gold particles (size between 2 and 6 nm) generated by gas evaporation have been investigated by high resolution TEM. Penta-twinned particles differ from quasi-crystals in the following way: the five coherent twin boundaries separating the twin oriented segments do not join up along a common edge. The lattice parameter is reduced by 4 - 5 % in comparison to that of bulk gold. The formation of the penta-twinned particles is proposed to occur by particle collision. The particles were observed to be crystalline at ambient temperature. Acknowledgments The authors acknowledge the continual encouragement of this study by Prof. Dr. E. Zeitler. The financial support by the BMFT (contract No. 03 M 0023 4) is appreciated;
