Isoscalar E 2 strength in sup 16 O from the ( e , e prime. alpha. ) reaction

We have measured the first complete angular correlations of {alpha}-particle emission from the {sup 16}O isoscalar giant quadrupole resonance (GQ{sub 0}R) following excitation by inelastic electron scattering. Analysis of these determines the GQ{sub 0}R strength distribution and resolves a discrepan...

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