Results are reported from a streamer chamber experiment performed at Stanford Linear Accelerator Center (SLAC) to study the production of the PHI(1020) in OZI-allowed and forbidden processes in ..pi../sup +/P interactions at 16 GeV/c. Production properties of the anti K*/sup 0/(896) are also studied and discussed. The data consisted of 300,000 streamer chamber photographs of eta/sup +/P interactions and information from Cerenkov and scintillation counters recorded on magnetic tapes. The PHI(1020) resonances are observed in the semi-inclusive reactions: eta/sup +/ + P ..-->.. PHI..lambda../sup 0/ + chi; eta/sup +/ + P ..-->.. PHIK/sub s//sup 0/ + chi. No clear PHI(1020) resonance is seen in the inclusive reaction eta/sup +/ + P ..-->.. PHI + chi. It is estimated that at least 35% of PHI's are produced in association with a pair of strange particles. The longitudinal momentum distribution of anti K*/sup 0/(896), expressed in terms of Feynman variable Xf, is compared with the predictions of the quark fusion model; it is observed that the model reproduces well the experimentally observed spectrum.
