title: Electronic spectroscopy of the Au-Xe complex.
abstract: We report electronic spectra of the Au-Xe complex for the first time. The transitions are recorded in the vicinity of the Au atomic 6p<-- 6s transitions. Structured spectra are found close to both the 6(2)P(1/2) and 6(2)P(3/2) states. The former is assigned as a (2)Pi(1/2) state in line with previous work on Au-Ar and Au-Kr; the possible assignment of the second spectrum is discussed. In addition, a large basis set extrapolated RCCSD(T) potential energy curve for the ground state, X(2)Sigma(+), is presented and derived spectroscopic parameters reported. More qualitative calculations are presented for electronically-excited states which arise from the Au(5(2)D) + Xe and Au(6(2)P) + Xe asymptotes, as well as some higher-lying states. The ab initio results are employed in the assignment of the reported spectra.
