Multifragmentation calculated with relativistic forces

  • Published:
Acta Physica Hungarica New Series Heavy Ion Physics

Abstract

A saturating hamiltonian is presented in a relativistically covariant formalism. The interaction is described by scalar and vector mesons, with coupling strengths adjusted to nuclear matter. No explicit density dependence is assumed and the momentum dependence results from the relativistic expansion. The hamiltonian is applied in a QMD calculation to determine the fragment distribution in O+Br collisions at different energies (50–200 Me V/u) to test the applicability of the model at low energies. The results are compared with experiment and with previous non-relativistic calculations.
