  The study of pho­to­pro­duc­tion of mesons is a prime tool in un­der­stand­ing the prop­er­ties of strong in­ter­ac­tions. The only pho­to­pro­duc­tion re­ac­tion on deuteron with two-body final state is co­her­ent pion pho­to­pro­duc­tion re­ac­tion. Sev­eral the­o­ret­i­cal stud­ies are being car­ried out on the pion pho­to­pro­duc­tion on deuterons since sev­eral decades. On the ex­per­i­men­tal side, the ac­cel­er­a­tor and de­tec­tor tech­nol­ogy has im­proved the de­vel­op­ments. In the re­cent years, mea­sure­ments of ten­sor an­a­lyz­ing pow­ers as­so­ci­ated with co­her­ent and in­co­her­ent pion pho­to­pro­duc­tion are also being car­ried out at the VEPP-3 elec­tron stor­age ring. In one of the re­cent mea­sure­ments, Rachek et al"*" have ob­served dis­crep­ancy be­tween the­ory and ex­per­i­ment at higher pho­ton en­er­gies and have sug­gested for im­prove­ment of the the­o­ret­i­cal mod­els. In a more re­cent analy­sis,"**" the role of D-wave com­po­nent on spin asym­me­tries have been iden­ti­fied. In view of these de­vel­op­ments, the pur­pose of the pre­sent con­tri­bu­tion is to study co­her­ent pion pho­to­pro­duc­tion on deuterons using model in­de­pen­dent ir­re­ducible ten­sor for­mal­ism de­vel­oped ear­lier to study the pho­to­dis­in­te­gra­tion of deuterons."***"
