Abstract: (APS)
Analysis of the multiple angular-correlation functions for the sequential decays ψ′(1−)→γ+χ,χ→MM¯, where M is a spinless meson, and ψ′(1−)→γ1+χ,χ→γ2+ψ, ψ(1−)→ll¯, when the ψ′ is formed in e+e− collisions, shows that these can unambiguously distinguish between the spin assignments sχ=0. 1, or 2 for the intermediate states occuring in these decays, as well as determine the multipole amplitudes contributing to the radiative transitions. No dynamical assumptions are made beyond the conservation of angular momentum and parity; recoils are fully taken into account.- PSI(3700): RADIATIVE DECAY
