Model independent approach to coherent photo pion production on deuterons

Deuteron being the simplest nuclei with one proton, neutron and electron, can be used to study reactions involving proton, neutron and electrons. The processes that can be studied using deuteron are photodisintegration, photo-production and electro-production. Photo-production can take place through coherent and incoherent processes. In view of the observations made about the irreducible tensor amplitudes and the unpolarized differential cross section, analysis of the result at the near threshold energies has been presented
