The Nuclear Matter Equation of State Including Light Clusters

摘要

The equation of state (EOS) of nuclear matter at moderate temperature and density with various proton fractions is considered, in particular the region of medium excitation energy given by the temperature range T < 30 MeV and the baryon density range pfi < 10142 g/cnr In addition to the mean-field effects, the formation of few-body correlations, in particular the light bound clusters up to the alpha particle (1 < A < 4), is of interest. Calculation based on the relativistic mean-field theory with the parameter set TM1 is presented. We show results for different values of the asymmetry parameter, and (3 equilibrium is considered as a special case. The medium modification of the light clusters is described by self-energy and Pauli blocking effects using an effective nucleon-nucleon interaction potential.
