The neutron decay of the giant resonance region between 13.0 and 18.0 MeV in /sup 90/Zr has been studied in an (..cap alpha..,..cap alpha..'n) coincidence experiment at E/sub ..cap alpha../ = 104 MeV. In the region of the giant quadrupole resonance between 13 and 16 MeV, additional strength with multipolarity L> or =4 was identified. For the resonant strength in the region of the giant monopole resonance, a direct decay component of about 12% can be estimated. In addition, evidence for a preequilibrium decay was found.
