Abstract

We have measured the first complete angular correlations of α-particle emission from the ${}^{16}O$ isoscalar giant quadrupole resonance ( ${GQ}_{0}$ R) following excitation by inelastic electron scattering. Analysis of these determines the ${GQ}_{0}$ R strength distribution and resolves a discrepancy between previous results from photonuclear excitation and inelastic α scattering.
