Abstract

Light clusters are included in the equation of state of nuclear matter within the relativistic mean-field theory. The effect of the cluster-meson coupling constants on the dissolution density is discussed. Theoretical and experimental constraints are used to fix the cluster-meson couplings. The relative light cluster fractions are calculated for asymmetric matter in chemical equilibrium at finite temperature. It is found that above T=5 MeV deuterons and tritons are the clusters in larger abundances. The results do not depend strongly on the relativistic mean-field interaction chosen.
