摘要：

The K + production cross section far below the free nucleon-nucleon production threshold is estimated in C-12 + C-12 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 K + yield in Ca-42 + Ca-42 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 et al.
