Proton and ..cap alpha..-particle emission from giant resonances in /sup 58/Ni excited by inelastic ..cap alpha.. scattering at 129 MeV into 0/sup 0/ has been investigated. By this choice of kinematic conditions quasifree contributions to the coincidence cross sections were eliminated. The sequential decay processes show a population of low-lying states which exceed Hauser-Feshbach predictions substantially, indicating >40% direct contributions to the charged particle decay of the isoscalar giant resonances near E-italic/sub x-italic/ = 17 MeV.
