A study of the Okubo-Zweig-Iizuka (OZI) rule in (pi)('+)d interactions at 10 GeV/c has been performed using the Large Aperture Solenoid Spectrometer (LASS) at the Stanford Linear Accelerator Center. Measurements of the cross sections (sigma)((pi)('+)n (--->) (phi)p) = 179 (+OR-) 72 nb and (sigma)((pi)('+)p (--->) (phi)(DELTA)('++)) = 172 (+OR-) 75 nb for the OZI forbidden reactions (pi)('+)n (--->) (phi)p and (pi)('+)p (--->) (phi)(DELTA)('++) are consistent with the hypothesis of the phi being produced solely by its nonstrange quark component as determined from the octet-singlet mixing angle resulting from application of the Gell-Mann-Okubo mass formula to the vector meson nonet. A cross section upper limit for the interesting OZI rule associated reaction (pi)('+)n (--->) K('+)(phi)(LAMDA) is measured to be (sigma)((pi)('+)n (--->) K('+)(phi)(LAMDA)) ) (phi)'p)B((phi)' (--->) K('+)K('-)(pi)('+)(pi)('-)) = 528 (+OR-) 290 nb. An upper limit for the K(,s)('0)K('(+OR-))(pi)('(-OR+)) decay mode of the phi prime is established as a function of the phi prime mass; *USDOE Report IS-T-983. This work was performed under Contract W-7405-eng-82 with the U.S. Department of Energy.
