The total cross sections of K/sup +/ and K/sup -/ mesons on protons have been measured between 3 and 19 Bev/c at the Brookhaven alternating gradient synchrotron. The data were obtained from measurements of attenuation in a liquid hydrogen target: The K mesons were defined in momentum by magnetic deflection and a scintillation counter telescope. They were identified by measuring the velocity with a highpressure gas-filled Cherenkov counter. Values of the cross sections were obtained at intervals of approximates 1 Bev/c with an error for each value of approximately 5%. sigma /sub t/( sup +/p) is, within errors, constant over the entire momentum range with a value of 18.4 mb. sigma /sub t/ (K/sup -/p) decreases gradually from a value of 28 mb at 4 Bev/c to 21.8 mb at 19 Bev/c. The cross sections are significantly different up to the highest momenta reached in this experiment. (auth)
