Observation of eta-c and other structures in the radiative decay psi to gamma eta pi-plus pi-minus
The Mark III detector at SPEAR was used 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 …

Computational Studies on the Effective Properties of Two-Phase Heterogeneous Media
… by extrapolating the data to zero radius, are &eta c=0.9614 ± 0.0005, 0.8647 ± 0.0006 and 0.7295 ± 0.0006 for circles, squares and equilateral triangles, respectively. These results show that the noncircular shapes and corner angles in the disk geometry tend to increase the interparticle …
