A resonance X(3872), first observed in the decays B\ensuremath→KX, has been seen to decay to J/\ensuremathψ\ensuremathπ+\ensuremathπ^\ensuremath-. The \ensuremathπ+\ensuremathπ^\ensuremath- mass spectrum peaks near its kinematic upper limit, prompting speculation that the dipion system may be in a \ensuremathρ0. The decay X(3872)\ensuremath→J/\ensuremathψ\ensuremathω also has been observed. The reaction \ensuremathγ\ensuremathγ\ensuremath→J/\ensuremathψ\ensuremathπ+\ensuremathπ^\ensuremath- has been studied. Consequently, angular distributions in decays of J/\ensuremathψ(\ensuremathρ0,\ensuremathω) states near threshold are of interest, and results are presented.
