摘要：

If density isomers exist they can be detected by measuring the excitation function of subthreshold kaon production. When the system reaches the density where the density isomer has influence on the equation of state (which depends on the beam energy and on the optical potential), we observe a jump in the cross section of the kaons whereas other observables change little. Above threshold LAMBDA'sBAR or p'sBAR may be used to continue the search. This is the result of microscopic Boltzmann-Uehling-Uhlenbeck calculations.
