Photoproduction of an isovector rho pi state at 1775 MeV

Evidence is presented for the charge-exchange photoproduction, in two distinct reactions, of an isovector {rho}{pi} state of mass {similar to}1775 MeV. Results of an analysis of the decay-angular distributions are also presented, from which it is concluded that {ital J}{sup {ital P}}=1{sup {minus}},...

Zusammenfassung:	Evidence is presented for the charge-exchange photoproduction, in two distinct reactions, of an isovector {rho}{pi} state of mass {similar to}1775 MeV. Results of an analysis of the decay-angular distributions are also presented, from which it is concluded that {ital J}{sup {ital P}}=1{sup {minus}}, 2{sup {minus}}, or 3{sup +}.
