Abstract
The proton and neutron decay of the giant monopole resonance in Zr-90 is analyzed in terms of collective and statistical doorway states. For this purpose the hybrid model of the decay is used in the context of channel particle competition. The semidirect components are compatible with the particle-hole continuum random-phase-approximation calculati ons. The protons spectra are found to be predominantly statistical whi le the neutron spectra contain semidirect contributions.
