Abstract: The production of the tensor mesons f/sup 0/(1270) and K/sup *//sup 0/(1430) and the scalar meson S(975) have been observed in e/sup +/e/sup -/ annihilation at 29 GeV center-of-mass energy, by use of data obtained with the High-Resolution Spectrometer at the storage ring SLAC e/sup +/e/sup -/ PEP. The mean multiplicities for meson momenta greater than 1450 MeV/c are = 0.11 +- 0.04, = 0.10 +- 0.0 6, and = 0.05 +- 0.02 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 of the S meson.
