Dependence of the $^{12}$C($\vec{\gamma}$,pd) reaction on photon linear polarisation

Nuclear Experiment 2008-11-26 v1

Abstract

The sensitivity of the 12^{12}C(γ,pd)(\vec{\gamma},pd) reaction to photon linear polarisation has been determined at MAMI, giving the first measurement of the reaction for a nucleus heavier than 3^{3}He. Photon asymmetries and cross sections were measured for EγE_{\gamma}=170 to 350 MeV. For EγE_{\gamma} below the Δ\Delta resonance, reactions leaving the residual 9^{9}Be near its ground state show a positive asymmetry of up to 0.3, similar to that observed for 3^{3}He suggesting a similar reaction mechanism for the two nuclei.
