Exclusive diffractive dissociation of K/sub L/ mesons at high energies

Using the hadronic component of the Fermilab broad band neutral beam, we have observed diffractive dissociation of K/sub L/ mesons with a carbon target into the exclusive final states Ks π+π-, K*(890)+-π-+, Ks rho0, Ks ω0, and Ks phi, but not Ks psi. The diffractive production cross section for these states is not strongly dependent on incident energy varying at most by 30% between 75 and 150 GeV. The shapes of the mass distributions do not change appreciably as a function of lab energy. The ratio of the diffractive mass threshold production of K*(890)+-π-+, Ks rho0, Ks ω0 and Ks phi is compared with results of two other experiments at lower lab energies with charged kaon beams on a hydrogen target
