Journal ArticleDOI
Photoemission spectra of C60- : electron-phonon coupling, Jahn-Teller Effect, and superconductivity in the fullerides
TL;DR: In this paper, the electron-phonon coupling constants were derived from the intensity of the excitation of phonons in high-resolution photoemission spectra, which support superconductivity.

Stable configurations of carbon clusters: Chains, rings, and fullerenes.

Electronic shells or molecular orbitals: Photoelectron spectra of Ag−n clusters
Abstract: Photoelectron spectra of Ag−n clusters with n=1–21 recorded at different photon energies (hν=4.025, 4.66, 5.0, and 6.424 eV) are presented. Various features in the spectra of Ag−2–Ag−9 can be assigned to electronic transitions predicted from quantum chemical ab initio calculations. While this comparison with the quantum chemical calculations yields a detailed and quantitative understanding of the electronic structure of each individual cluster, a discussion in terms of the shell model is able to explain trends and dominant patterns in the entire series of spectra up to Ag−21.
Journal ArticleDOI
Vibrational spectroscopy of clusters using a "magnetic bottle" electron spectrometer
TL;DR: In this paper, a high resolution magnetic bottle-type time-of-flight electron spectrometer suitable for the study of mass-separated metal and semiconductor cluster anions is described.
Journal ArticleDOI
A comparison of photoelectron spectroscopy and two-photon ionization spectroscopy : excited states of Au2, Au3, and Au4
TL;DR: In this article, photo-electron spectra of Au−n with n=2−4 are reported, which serve as a map of the electronic states of a cluster, while the high resolution of the resonant two-photon ionization (R2PI) method gains information about the symmetry of the states.
