英文摘要	Vibrational state-selective resonant two-photon photoelectron spectra have been obtained via a triplet intermediate state ((3)Sigma(-)) of AuS- near its detachment threshold using high-resolution photoelectron imaging of cryogenically cooled AuS- anions. Four vibrational levels of the (3)Sigma(-) excited state are observed to be below the detachment threshold. Resonant two-photon absorptions through these levels yield vibrational state-selective photoelectron spectra to the (3)Sigma(-) final state of neutral AuS with broad and drastically different Franck-Condon distributions, reflecting the symmetries of the vibrational wave functions of the (3)Sigma(-) intermediate state. The (3)Sigma(-) excited state is spin-forbidden from the (1)Sigma(-) ground state of AuS- and is accessed due to strong relativistic effects. The nature of the (3)Sigma(-) excited state is confirmed by angular distributions of the photoelectron images and quantum calculations.
