After making corrections for Fermi motion and shadowing, the data indicate that K+ production near threshold is stronger in pp- than in pn-induced reactions. However, most of this difference could be made up by the unobserved K0 production in the pn case.","authors_text":"A. Dzyuba, A. Kacharava, A. Khoukaz, A. Polyanskiy, C. Wilkin, F. Rathmann, H.
