Coherent K/sub S/ regeneration on protons from 30 to 130 GeV/c

Precise measurements at t = 0 of the K/sub L/p ..-->.. K/sub S/p amplitude (modulus and phase) were made. Over 50 000 K/sub pi2/ decays along with normalizing K/sub mu3/ events were detected behind a 7.2-m-long liquid-hydrogen regenerator. The momentum dependence of the modulus and phase are presented, and the results are combined with those of other experiments to extract the relevant parameters of ..omega.. exchange.
