We have measured the quantum numbers J{sup PG} of the KsK{sup {+-}}{pi}{sup {+-}} system produced in the diffraction dissociation process pp{yields}pf(K{sup 0}sK{sup {+-}}{pi}{sup {+-}})ps at 800 GeV/c. We observe two clear peaks at 1282{+-}0.6 MeV/c{sup 2}, {gamma}=25{+-}0.5 MeV/c{sup 2} and 1432{+-}0.6 MeV/c{sup 2}, {gamma}=51{+-}0.9 MeV/c{sup 2}. A partial wave analysis shows that the resonances we observe have J{sup PG}=1{sup ++}a0{pi} for the first peak, and J{sup PG}=1{sup ++}K*K for the second peak. Thus, they can be identified as the f1(1285) and f1(1420), respectively. No evidence for a signal at {approx_equal}1510 MeV/c{sup 2} is obtained.
