K+ production on carbon and lead was measured for proton beam kinetic
energies from 1.2 up to 2.5 GeV. It was found that the high momentum t
ail of the kaon spectrum extends beyond the kinematical limit for the
elementary reaction. The influence of the internal motion of nucleons
on the particle production was studied within the folding model.
