In an experiment with the CERN 2m deuterium bubble chamber the reaction K + d→K o pp (1) and the related reaction K + n→K o p (2) are studied at an incident momentum of 4.6 GeV/ c . The cross section for the latter reaction is found to be slightly larger than the cross section for the reaction K − p → K o n at the same energy. The corresponding differential cross sections agree within the rather large uncertainties. The forward amplitude for reaction (2) is predominantly real. Moreover, the total and forward differential charge exchange cross section values are compatible with those predicted on the basis of an SU (3) sum rule. A comparison of the K ± -charge exchange differential cross sections with the predictions of a Regge pole model is also presented.

Differential cross sections for K−p→K¯0n and K+n→K0p have been measured at 3, 4, and 6 GeV/c using a data sample of 6000 events. Contrary to simple exchange-degenerate models, the ratio of K+ to K− cross sections was found to be approximately 1.35, with little dependence on either s or t. Both reactions show a shallow dip near the forward direction, suggesting the importance of spin-flip amplitudes.

Line Reversal Breaking in K+- n Charge Exchange and K+- n --> K0 Delta (1236) at 4-GeV/c and 6-GeV/c

Differential cross sections for the line-reversed reaction pairs K + 0p → K o Δ ++ (1236), K − n → K ̄ o Δ − (1236) and K − p → K ̄ o n , K + n → K o p have been measured with good statistics at 4 and 6 GeV/ c . The line reversal breaking for the Δ (1236) reactions is found to have no significant variation with energy and to be larger than for the charge exchange reactions. The cross sections for all four reactions show a dip in the forward direction, indicating the importance of spin-flip amplitudes.
