Abstract In the fusion reactions90Zr(89Y,p)178Pt and90Zr(89Y,α)175Ir the sum energy of all emittedγ rays as well as the energy of the promptly emitted charged particle were measured. From these data the mass-excess values for the evaporation residues178Pt and175Ir were extracted to beΔ(178Pt)=(−32.4±1.1)MeV/c2 andΔ(175Ir)=(−32.0±1.2) MeV/c2. The method provides absolute mass values for nuclides far from stability which can be produced in fusion reactions as evaporation residues in the 1p or 1α channel. The sources of the experimental uncertainties of the method are discussed, and the potential for considerable improvements is outlined.
