Abstract

Zero electron kinetic energy (ZEKE) spectroscopy and photodetachment cross section measurements have been carried out on Au<sup> - </sup ₆. The transition frequencies of ZEKE peaks and resonance peaks are nearly identical, consistent with the proposal that the excited negative ion of Au6 has a geometry quite similar to that of neutral Au6, and supporting the picture of the resonances as weakly bound surface states.' From these studies the 0–0 transition frequency between Au^-₆ and Au6 is measured to be 16 541±17 cm&#8722;1, and the vibrational frequencies for the neutral Au6 ground state, the Au^-₆ ground state, and the (Au^-₆)* anion excited electronic state are 107, 73, and 107 cm&#8722;1, respectively. Lastly, we observe evidence for a previously unreported resonance transition to the excited anion which we suggest is the 0–0 transition of Au^-₆ to (Au^-₆)*.
