TY - INPR A1 - Konopka, Jens A1 - Stöcker, Horst A1 - Greiner, Walter T1 - On the impossibility of temperature extraction from heavy ion induced particle spectra N2 - Spectra of various particle species have been calculated with the Quantum Molecular Dynamics (QMD) model for very central collisions of Au+Au. They are compatible with the idea of a fully stopped thermal source which exhibits a transversal expansion besides the thermal distribution of an ideal gas. How- ever, the microscopic analyses of the local flow velocities and temperatures indicate much lower temperatures at densities associated with the freeze-out. The results express the overall impossibility of a model-independent determi- nation of nuclear temperatures from heavy ion spectral data, also at other energies (e.g. CERN) or for other species (i.e. pions, kaons, hyperons) KW - QMD KW - Kollisionen schwerer Ionen KW - Molekulare Dynamik KW - ideales Gas KW - Quantum Molecular Dynamics KW - heavy ion collisions KW - ideal gas KW - QMD Y1 - 2006 UR - http://publikationen.ub.uni-frankfurt.de/frontdoor/index/index/docId/2967 UR - https://nbn-resolving.org/urn:nbn:de:hebis:30-24307 ER -
