Abstract

The total cross sections of

K^{+}

and

K^{-}

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 high-pressure gas-filled Cerenkov counter. Values of the cross sections were obtained at intervals of ∼1 BeV/c with an error for each value of approximately 5%.

σ_{t} (K^{+} p)

is, within errors, constant over the entire momentum range with a value of 18.4 mb.

σ_{t} (K^{-} p)

decreases gradually from a value of 28 mb at 4 BeV/c to 21.6 mb at 19 BeV/c. The cross sections are significantly different up to the highest momenta reached in this experiment.
