  We analyze recent inclusive data on K+ production in proton induced
Lambda-multi nucleon knock out on Carbon 12. We describe collective effects
among the incoming p and bound nucleons in a pi, rho rescattering model via the
excitation of various baryon resonances. We find the dominance of Lambda N and
Lambda NN final states for K+ momenta below 200 MeV/c, while for momenta above
400 MeV/c the data reflect a continuum with an unbound Lambda together with the
bound residual nucleus C 12.
