We have studied the diffractive production of mesons with natural and unnatural parity at high energy. Partial wave analyses of the K..pi.. and KK systems give evidence for J/sup p/ = 4/sup +/ mesons with masses near 2.06 and 2.00 GeV, respectively. The Breit--Wigner behavior of the resonant phases is clearly seen in the data. Evidence for unnatural parity states comes from a partial wave analysis of the Lp system. We find three broad states with J/sup P/ = 2/sup -/, 3/sup +/ and 4/sup -/ and masses 2.26, 2.32 and 2.49 GeV, respectively. An interpretation in terms of resonances is consistent with the data.
