Observation of eta-c and other structures in the radiative decay psi to gamma eta pi-plus pi-minus
… to observe the exclusive radiative decay [...] A spin-parity analysis was performed to determine the quantum numbers of the resonances responsible for this structure. However, the result was seen to be model dependent, so that it was not possible to conclusively resolve the underlying structure in …

Spin parity studies of the eta pi decay of the A2 meson and investigation of the A2 production mechanism in the reaction pi-minus proton goes to A2-minus proton
The results of a spin parity analysis of the nv-decay mode of the A-meson produced in the reaction A2-p -A2-pare presented. Data for the analysis are drawn from bubble chamber experiments between 3.9 and 16 GeV/c. The analysis favors JP=Z+ for both the upper and lower regions of the AZ' Possible …

A-2 meson production in pi-minus proton interactions at five BeV
… reported at other incident pion momenta. The spin-parity analysis of the Ppi decay mode yields results p + which are consistent with a J = 2 assignment for both halves of the A2"" The angular distribution of the decay plane indicates a J = 2 spin state with alkl = 1 component along the normal …
