Abstract

In the present work we report the study of gold particles using HREM and image processing. Particles which are not conventional fcc are discussed as well as penta-twinned particles which show twin boundaries that do not join along a common point. It is shown that there are particles with an hcp structure. This structure is probably due to repeated faulting and excess vacancies.
