Abstract: | In this paper we describe the application of a special form of electron photodetachment spectroscopy, zero electron kinetic energy (ZEKE) spectroscopy, to the study of cold metal cluster anions. From this study we have obtained vibrational and thus structural information of several neutral and charged clusters, e.g. Au 2 ?/0 , Ag 3 ?/0 , Sn 2 ?/0 and Al 3 ?/0 . In addition, in separate measurements of the relative photodetachment cross section of Au 2 ? , we have discovered sharp resonances which are due to electronic autodetachment from a short lived excited state. |
