Abstract
We have measured the first complete angular correlations of α-particle emission from the isoscalar giant quadrupole resonance (R) following excitation by inelastic electron scattering. Analysis of these determines the R strength distribution and resolves a discrepancy between previous results from photonuclear excitation and inelastic α scattering.
