For the compound nucleus179Au formed at an excitation energy of 26 MeV in the fusion reaction90Zr+89Y, the energy spectra of promptly emitted protons, α particles and γ rays were measured in concidence with the evaporation residues. On the basis of the measured total decay energy, the 1 p and 1 α decay channels were separated from all other evaporation-residue channels. The energy spectra and absolute cross sections, together with previously measured excitation functions for various decay channels, are successfully described by statisticalmodel calculations with the Monte Carlo code CODEX. © 1991 Springer-Verlag.
