We present cross sections and angular distributions for the reaction K + d → K o pp at 865, 970, 1210, 1365 and 1585 MeV/ c . Making corrections for deuterium effects, we observe the following features of the elastic charge exchange process K + n → K 0 p: a) the c.m. angular distribution becomes increasingly peripheral as the momentum increases from 800 to 1600 MeV/ c ; b) the forward amplitude is largely real. Attempts to describe the data either in terms of a Regge model or in terms of dominance by an elastic P 1 2 isoscalar KN resonance are discussed.
