Abstract: (APS)
We derive double polarization observables for the photodisintegration of He4 with an incident polarized photon beam. In particular we study the effect of the ground state α-particle D wave on these observables in a simple nuclear model. We find that in general the double polarization observables offer no clear advantage to the corresponding variables studied in the single polarization He4(γ,d→)2H reaction. However, the photon asymmetry Σ appears as a promising observable for the study of ground state effects.
