The [ital K][sup +] production cross section far below the free nucleon-nucleon production threshold is estimated in [sup 12]C+[sup 12]C collisions using simulations of the Boltzmann and the Boltzmann-Langevin equations. Fluctuations increase substantially the cross sections especially at low beam energies. We also give an estimate of the [ital K][sup +] yield in [sup 42]Ca+[sup 42]Ca collisions at an incident energy of 90 MeV/nucleon in order to compare our result to recent experimental data obtained in a similar system by Julien [ital et] [ital al].
