Abstract:

The dimer dissociation energies of gold cluster ions Au + n , n = 9, 11, 13, 15 have been determined with an extension of a recently developed model-independent method. Monomer-dimer decay pathway branching ratios provide the energy dependent process which is needed in this method. The measured values are D 2 (Au + 9 ) = 3.66(8)(9) eV, D 2 (Au + 11 ) = 4.27(11)(8) eV, D 2 (Au + 13 ) = 4.50(9)(7) eV and D 2 (Au + 15 ) = 4.29(10)(6) eV.
