The production of the tensor mesons, integral/sup 0/(1270) and K*/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, using data obtained with the HRS detector at the PEP storage ring. The mean multiplicities for meson momenta greater than 1450 MeV/c are = 0.11 +- 0.04, = 0.10 +- 0.06, 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 possibility of a large strange quark component in the S meson structure is suggested by the data.
