Photodisintegration of aligned deuterons at astrophysical energies using linearly polarized photons

Abstract

Following the model independent approach to deuteron photodisintegration with linearly polarized $\gamma -$rays, we show that the measurements of the tensor analyzing powers on aligned deuterons along with the differential cross section involve five different linear combinations of the isovector $E{1}_v^j;j=0,1,2$ amplitudes interfering with the isoscalar $M{1}_s$ and $E{2}_s$ amplitudes. This is of current interest in view of the recent experimental finding \cite{blackston1} that the three $E{1}_v^j$ amplitudes are distinct and also the reported experimental observation \cite{sawatzky} on the front-back (polar angle) asymmetry in the differential cross section.
