This paper reports cross-section measurements for the /rho//sup 0/ and /ital K//sup */(890) vector mesons produced in /ital e//sup +/e/sup /minus// annihilation at /radical//ital s/ =29 GeV. The data, which were taken with the High Resolution Spectrometer operating at the SLAC colliding-beam facility PEP,correspond to an integrated luminosity of 291 pb/sup /minus/1/. The measured multiplicities for fractional momentum /ital x//gt/0.05 are /ital N//sub /rho//sup 0//=0.79/plus minus/0.04 and /ital N//sub /ital K//sup *0/(890)/=0.53/plus minus/0.04. The measured fragmentation functions agree well with the predictions of the Lund model and when extrapolated to threshold, the corresponding total multiplicities are /ital N//sub /rho//sup 0//=0.90/plus minus/0.05 and /ital N//sub /ital K//sup *0/(890)/=0.59/plus minus/0.05.
