Non-perturbative treatment of hyperfine interaction in charmonium
Description
We give arguments that the wave function of etac is relativistic and strongly localized while that of etac, though non-relativistic, looks quite different from what is naively expected. This has consequences for the overlap integrals with PSI and PSI' and may solve the problems associated with magnetic transitions. The hadronic width of etac is expected around 20 MeV, that of N'c can become very small. (orig.)
