The first exclusive measurements of the spin transfer parameter D-NN in the reaction (p) over right arrow p --> pK(+)<(Lambda)over right arrow> has been performed at Saturne with the polarized beam and with the DISTO spectrometer. The results suggest an OBE mechanism dominated by kaon exchange.

Abstract
The first exclusive measurements of the spin transfer parameter D-NN in the reaction (p) over right arrow p --> pK(+)<(Lambda)over right arrow> has been performed at Saturne with the polarized beam and with the DISTO spectrometer. The results suggest an OBE mechanism dominated by kaon exchange.
