K+ meson production by 2.1-GeV/nucleon Ne, d, and p projectiles on NaF and Pb targets has been measured. The cross sections depend exponentially upon the kaon energy in the nucleon-nucleon c.m. frame, with an inverse slope T0 larger than the values obtained from comparable proton and π- spectra. The angular distribution in this frame is approximately isotropic. We find that σ(Ne+Pb→K+X)σ(Ne+NaF→K+X)>σ(d+Pb→K+X) σ(d+NaF→K+X). Data are compared with theoretical predictions.
