Title: Elliptic Flow in Heavy-Ion Collisions near the Balance Energy

Abstract

The proton elliptic flow in collisions of {sup 48}Ca on {sup 48}Ca at energies from 30 to 100thinspthinspMeV/nucleon is studied in an isospin-dependent transport model. With increasing incident energy, the elliptic flow shows a transition from positive to negative flow. Its magnitude depends on both the nuclear equation of state (EOS) and the nucleon-nucleon scattering cross section. Different elliptic flows are obtained for a stiff EOS with free nucleon-nucleon cross sections and a soft EOS with reduced nucleon-nucleon cross sections, although both lead to vanishing in-plane transverse flow at the same balance energy. {copyright} {ital 1999} {ital The American Physical Society}
