title: Vacuum-ultraviolet laser-excited spectra of Xe(2).
abstract: Fluorescence excitation of Xe(2) at 149.0 nm has been observed using a pulsed supersonic jet for dimer formation and cooling and using tunable coherent VUV radiation from four-wave mixing in Mg vapor for excitation. The resolved vibronic structure resulting from isotopic Xe(2) molecules has yielded unambiguous vibrational numbering (upsilon'=37-46), giving the following constants for the first O(+)(u) excited state of Xe(2): T(e) = 63 796(6) cm (-1), omega'(e) = 124.86(30) cm(-1), omega(e)X'(e) = 0.937(3) cm(-1), and D(e) = 4446(7) cm(-1).
