Av. Afanasev et Ap. Szczepaniak, Charge exchange rho(0)pi(+) photoproduction and implications for searches for exotic mesons - art. no. 114008, PHYS REV D, 6111(11), 2000, pp. 4008
We analyze the processes <(gamma)over right arrow>+p-->rho(o)pi(+)n at low
momentum transfer focusing on the possibility of the production of an exoti
c J(PC) = 1(-+) meson state. In particular we discuss polarization observab
les and conclude that linear photon polarization is instrumental for separa
ting the exotic wave.
