The direct and statistical neutron decay of the isoscalar giant dipole resonance was studied in Zr90, Sn116, and Pb208 using the (α,α'n) reaction at a bombarding energy of 200 MeV. The spectra of fast decay neutrons populating valence hole-states of the Z,N-1 nuclei were analyzed, and estimates for the branching ratios were determined. The results were compared to recent continuum random-phase approximation calculations.
