Abstract
The production of the tensor mesons and and the scalar meson has been observed in annihilation at 29 GeV center-of-mass energy by use of data obtained with the high-resolution spectrometer at the SLAC storage ring PEP. The mean multiplicities for meson momenta greater than 1450 MeV/c are , , and per hadronic event. The fragmentation functions of the tensor mesons are in good agreement with the predictions of the Webber cluster model. The data are consistent with a predominant strange-quark content on the meson.
