Belle data for the {pi}{pi} mass spectrum in X(3872){yields}{pi}{sup +}{pi}{sup -}J/{psi} are well fitted by {rho}+J/{psi} with J{sup PC}=1{sup ++}, but are poorly fitted by the {pi}{pi} S-wave. This rules out quantum numbers 1{sup +-}, 2{sup --} and 3{sup --}. Formulas for partial wave amplitudes are given for all likely J{sup PC} and decay modes of the 3941 MeV peak which Belle observe in {omega}+J/{psi}. Angular correlations involving up to five angles may allow a spin-parity determination, even with quite low statistics. Special attention is given to the case where X(3872) is a cusp or quasi-bound state with the same quantum numbers as the 3941 MeV peak.
