PHOTOIONIZATION STUDIES OF TRANSITION-METAL CLUSTERS - IONIZATION-POTENTIALS OF SCNO (N=5-36)
The photoionization efficiency (PIE) spectra and ionization potentials are reported for scandium cluster monoxides (Sc(n)O, n = 5-36). As found for other transition metal clusters, strong dependence of ionization potential on cluster size is found for small clusters, with the ionization potentials of larger clusters decreasing relatively smoothly with increasing size. The IPs are 0.6-0.8 eV lower than that predicted by conducting spherical droplet model
