摘要：

Belle data for the pipi mass spectrum in X(3872)-->pi(+)pi(-)J/Psi are well fitted by rho+J/Psi with J(PC)=1(++), but are poorly fitted by the pipi S-wave. This rules out quantum numbers 1(+-), 2(--) and 3(--). Formulas for partial wave amplitudes are given for all likely J(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.
