A resonance X(3872), first observed in the decays B{yields}KX, has been seen to decay to J/{psi}{pi}{sup +}{pi}{sup -}. The {pi}{sup +}{pi}{sup -} mass spectrum peaks near its kinematic upper limit, prompting speculation that the dipion system may be in a {rho}{sup 0}. The decay X(3872){yields}J/{psi}{omega} also has been observed. The reaction {gamma}{gamma}{yields}J/{psi}{pi}{sup +}{pi}{sup -} has been studied. Consequently, angular distributions in decays of J/{psi}({rho}{sup 0},{omega}) states near threshold are of interest, and results are presented.
