Coulomb corrections to density and temperature in heavy ion collisions

Abstract

A recently proposed method, based on quadrupole and multiplicity fluctuations in heavy ion collisions, is modified in order to take into account distortions due to the Coulomb field. The classical and quantum limits for fermions are discussed. In the classical case we find that the temperature determined from ${}^{3}He$ and ${}^{3}H$, after the Coulomb correction, are very similar to those obtained from neutrons within the Constrained Molecular Dynamics (CoMD) approach. In the quantum case, the proton temperature becomes very similar to neutron's, while densities are not sensitive to the Coulomb corrections.
