摘要: Based on the UrQMD and CRAB analyzing program, HBT correlators of nucleons pions are calculated with beam energies ranging from SIS up to RHIC. It is found that correlator ratio between radii RO RS sensitive stiffness EoS. A relatively stiff EoS favored RO/RS pions. For two-nucleon correlation at energies, it both symmetry potential energy conditions constructing clusters late stage influence same power.
